Here's the typical cleanup patch that follows any large
set of patches. My testing organization is either too large
or too small, depending on how you look at it, sigh...

Ok, here's the cleanup patch I suggested you wait for. Have at it...
Subject: added little-endian pack/unpack options
This is the only enhancement in this patch, but it seemed unlikely
to bust anything else, and added functionality that it was very
difficult to do any other way. Compliments of David W. Sanderson.
Subject: op/regexp.t failed from missing arg to bcmp()
Subject: study was busted by 4.018
Subject: sort $subname was busted by changes in 4.018
Subject: default arg for shift was wrong after first subroutine definition
Things that broke in 4.018. Shame on me.
Subject: do {$foo ne "bar";} returned wrong value
A bug of long standing. How come nobody saw this one? Or if you
did, why didn't you report it before now? Or if you did, why did
I ignore you? :-)
Subject: some machines need -lsocket before -lnsl
Subject: some earlier patches weren't propagated to alternate 286 code
Subject: compile in the x2p directory couldn't find cppstdin
Subject: more hints for aix, isc, hp, sco, uts
Subject: installperl no longer updates unchanged library files
Subject: uts wrongly defines S_ISDIR() et al
Subject: too many preprocessors can't expand a macro right in #if
The usual pastiche of portability kludges.
Subject: deleted some unused functions from usersub.c
And fixed the spelling of John Macdonald's name, and included his
suggested workaround for a certain vendor's stdio bug...
Subject: added readdir test
Subject: made op/groups.t more reliable
Subject: added test for sort $subname to op/sort.t
Subject: added some hacks to op/stat.t for weird filesystem architectures
Improvements (hopefully) to the regression tests.

So far, 4.0 is still a beta test version. For the last production
version, look in pub/perl.3.0/kits@44.

I tried to take the strlen of an integer on systems without wait4()
or waitpid(). For some reason this didn't work too well...
In hash.c there was a call to dbm_nextkey() which needed to be
ifdefed on old dbm systems.
A pattern such as /foo.*bar$/ was wrongly optimized to do
tail matching on "foo". This was a longstanding bug that
was unmasked by patch 36.
Some systems have some SYS V IPC but not all of it. Configure
now figures this out.
Patch 36 put the user's PATH in front of Configures, but to make
it work right I needed to change all calls of loc to ./loc in
Configure.
$cryptlib needed to be mentioned in the Makefile.
Apollo 10.3 and Sun 3.5 have some compilation problems, so I
mentioned them in README.
Cray has weird restrictions on setjmp locations--you can't say
if (result = setjmp(...))
Random typos and cleanup.

Certain systems, notable Ultrix, set the close-on-exec flag
by default on dup'ed file descriptors. This is anti-social
when you're creating a new STDOUT. The flag is now forced
off for STDIN, STDOUT and STDERR.
Some yaccs report 29 shift/reduce conflicts and 59 reduce/reduce
conflicts, while other yaccs and bison report 27 and 61. The
Makefile now says to expect either thing. I'm not sure if there's
a bug lurking there somewhere.
The defined(@array) and defined(%array) ended up defining
the arrays they were trying to determine the status of. Oops.
Using the status of NSIG to determine whether <signal.h> had
been included didn't work right on Xenix. A fix seems to be
beyond Configure at the moment, so we've got some OS dependent
#ifdefs in there.
There were some syntax errors in the new code to determine whether
it is safe to emulate rename() with unlink/link/unlink. Obviously
heavily tested code... :-)
Patch 27 introduced the possibility of using identifiers as
unquoted strings, but the code to warn against the use of
totally lowercase identifiers looped infinitely.
I documented that you can't interpolate $) or $| in pattern.
It was actually implied under s///, but it should have been
more explicit.
Patterns with {m} rather than {m,n} didn't work right.
Tests io.fs and op.stat had difficulties under AFS. They now
ignore the tests in question if they think they're running under
/afs.
The shift/reduce expectation message was off for a2p's Makefile.

A few of the new features: (18 Oct)
* Perl can now handle binary data correctly and has functions to pack and unpack binary structures into arrays or lists. You can now do arbitrary ioctl functions.
* You can now pass things to subroutines by reference.
* Debugger enhancements.
* An array or associative array may now appear in a local() list.
* Array values may now be interpolated into strings.
* Subroutine names are now distinguished by prefixing with &. You can call subroutines without using do, and without passing any argument list at all.
* You can use the new -u switch to cause perl to dump core so that you can run undump and produce a binary executable image. Alternately you can use the "dump" operator after initializing any variables and such.
* You can now chop lists.
* Perl now uses /bin/csh to do filename globbing, if available. This means that filenames with spaces or other strangenesses work right.
* New functions: mkdir and rmdir, getppid, getpgrp and setpgrp, getpriority and setpriority, chroot, ioctl and fcntl, flock, readlink, lstat, rindex, pack and unpack, read, warn, dbmopen and dbmclose, dump, reverse, defined, undef.

Some of the enhancements from Perl1 included:
* New regexp routines derived from Henry Spencer's.
o Support for /(foo|bar)/.
o Support for /(foo)*/ and /(foo)+/.
o \s for whitespace, \S for non-, \d for digit, \D nondigit
* Local variables in blocks, subroutines and evals.
* Recursive subroutine calls are now supported.
* Array values may now be interpolated into lists: unlink 'foo', 'bar', @trashcan, 'tmp';
* File globbing.
* Use of <> in array contexts returns the whole file or glob list.
* New iterator for normal arrays, foreach, that allows both read and write.
* Ability to open pipe to a forked off script for secure pipes in setuid scripts.
* File inclusion via do 'foo.pl';
* More file tests, including -t to see if, for instance, stdin is a terminal. File tests now behave in a more correct manner. You can do file tests on filehandles as well as filenames. The special filetests -T and -B test a file to see if it's text or binary.
* An eof can now be used on each file of the <> input for such purposes as resetting the line numbers or appending to each file of an inplace edit.
* Assignments can now function as lvalues, so you can say things like ($HOST = $host) =~ tr/a-z/A-Z/; ($obj = $src) =~ s/\.c$/.o/;
* You can now do certain file operations with a variable which holds the name of a filehandle, e.g. open(++$incl,$includefilename); $foo = <$incl>;
* Warnings are now available (with -w) on use of uninitialized variables and on identifiers that are mentioned only once, and on reference to various undefined things.
* There is now a wait operator.
* There is now a sort operator.
* The manual is now not lying when it says that perl is generally faster than sed. I hope.

I didn't add an eval operator to the original perl because
I hadn't thought of any good uses for it. Recently I thought
of some. Along with creating the eval operator, this patch
introduces a symbolic debugger for perl scripts, which makes
use of eval to interpret some debugging commands. Having eval
also lets me emulate awk's FOO=bar command line behavior with
a line such as the one a2p now inserts at the beginning of
translated scripts.

[ Perl is kind of designed to make awk and sed semi-obsolete. This posting
will include the first 10 patches after the main source. The following
description is lifted from Larry's manpage. --r$ ]
Perl is a interpreted language optimized for scanning arbitrary text
files, extracting information from those text files, and printing
reports based on that information. It's also a good language for many
system management tasks. The language is intended to be practical
(easy to use, efficient, complete) rather than beautiful (tiny,
elegant, minimal). It combines (in the author's opinion, anyway) some
of the best features of C, sed, awk, and sh, so people familiar with
those languages should have little difficulty with it. (Language
historians will also note some vestiges of csh, Pascal, and even
BASIC-PLUS.) Expression syntax corresponds quite closely to C
expression syntax. If you have a problem that would ordinarily use sed
or awk or sh, but it exceeds their capabilities or must run a little
faster, and you don't want to write the silly thing in C, then perl may
be for you. There are also translators to turn your sed and awk
scripts into perl scripts.
