This allowed module authors to make subroutines that behaved like Perl builtins. Perl 5.003 was released June 25, 1996, as a security release.These simplify and facilitate many parsing, text-handling, and data-management tasks.Perl 5 version 20.0 documentation. metacpan.org.

The Cygwin emulation layer is another way of running Perl under Windows.

It is a long-standing result that the halting problem is undecidable, and therefore not even perl can always parse Perl.Perl also has many built-in functions that provide tools often used in shell programming (although many of these tools are implemented by programs external to the shell) such as sorting, and calling operating system facilities.A perl executable is included in several Windows Resource kits in the directory with other scripting tools.
