[inseparable changes from patch from perl5.003_07 to perl5.003_08]

 CORE LANGUAGE CHANGES

Subject: Bitwise op sign rationalization
From: Chip Salzenberg <chip@atlantic.net>
Files: op.c opcode.pl pod/perlop.pod pod/perltoc.pod pp.c pp.h pp_hot.c proto.h sv.c t/op/bop.t

    Make bitwise ops result in unsigned values, unless C<use
    integer> is in effect.  Includes initial support for UVs.

Subject: Defined scoping for C<my> in control structures
From: Chip Salzenberg <chip@atlantic.net>
Files: op.c perly.c perly.c.diff perly.h perly.y proto.h toke.c

    Finally defines semantics of "my" in control expressions,
    like the condition of "if" and "while".  In all cases, scope
    of a "my" var extends to the end of the entire control
    structure.  Also adds new construct "for my", which
    automatically declares the control variable "my" and limits
    its scope to the loop.

Subject: Fix ++/-- after int conversion (e.g. 'printf "%d"')
From: Chip Salzenberg <chip@atlantic.net>
Files: pp.c pp_hot.c sv.c

    This patch makes Perl correctly ignore SvIVX() if either
    NOK or POK is true, since SvIVX() may be a truncated or
    overflowed version of the real value.

Subject: Make code match Camel II re: functions that use $_
From: Paul Marquess <pmarquess@bfsec.bt.co.uk>
Files: opcode.pl

Subject: Provide scalar context on left side of "->"
From: Chip Salzenberg <chip@atlantic.net>

Subject: Quote bearword package/handle FOO in "funcname FOO => 'bar'"
From: Chip Salzenberg <chip@atlantic.net>
Files: toke.c

-=head2 Typeglobs and FileHandles
+=head2 Typeglobs
 
 Perl uses an internal type called a I<typeglob> to hold an entire
 symbol table entry.  The type prefix of a typeglob is a C<*>, because
 it represents all types.  This used to be the preferred way to 
 pass arrays and hashes by reference into a function, but now that
-we have real references, this is seldom needed.
+we have real references, this is seldom needed.  It also used to be the
+preferred way to pass filehandles into a function, but now
+that we have the *foo{THING} notation it isn't often needed for that,
+either.
 
-One place where you still use typeglobs (or references thereto)
-is for passing or storing filehandles.  If you want to save away
-a filehandle, do it this way:
-
-    $fh = *STDOUT;
-
-or perhaps as a real reference, like this:
-
-    $fh = \*STDOUT;
-
-This is also the way to create a local filehandle.  For example:
-
-    sub newopen {
-	my $path = shift;
-	local *FH;  # not my!
-	open (FH, $path) || return undef;
-	return \*FH;
-    }
-    $fh = newopen('/etc/passwd');

-See L<perlref>, L<perlsub>, and L<perlmod/"Symbols Tables"> for more
-discussion on typeglobs.  See L<perlfunc/open> for other ways of
-generating filehandles.
