I think you hit the nail on the head there.  The problem is indeed
that much interesting programming these days is "scripting" - ie.
lots of short single-purpose programs maintained in a collection of
programs rather than an application.

If you analyse what Perl has which other languages don't, it can be
mostly reduced to these items:

* Syntactic support for processing lines in a file, ie:

	while (<>) { ... }

  which is an astonishing piece of brevity.  It reads all the command line
  arguments, opens the files specified and hands them line-at-a-time to
  the code inside the while loop.  I think ExtLib has some functionality
  to do a small part of this.  It should be included in the standard
  distribution.

* Syntactic support for regular expression matching / substring extraction.

  (As discussed before.)

* No (visible) compilation required.

  #!/usr/bin/perl

  Very useful.  There was some discussion before about writing scripts
  starting with:

  #!/usr/bin/ocaml

* Certain idiomatic forms, such as:

	statement if condition;
  and:	statement unless condition;

  which reduce code size.

* Absolutely huge library.

  I'm trying to do my bit here by writing libraries, and specifically
  with perl4caml which allows you to use Perl libraries with OCaml.  A
  central CPAN-like resource would still be very useful.
