perl 3.0: (no announcement message available)perl-3.000

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.
