Although I have never used CPAN, I have found that in general Perl has an excellent community of programmers and library creators who are happy to share code... I specifically recall a free module which performed recursive descent and saved me untold amounts of time.

Perl also has what is IMHO one of the oddest/coolest subcultures of any language, centered around creating working programs that show a picture in the code. The classic is the so-called camel code:

#!/usr/bin/perl -w                                      # camel code
use strict;

                                           $_='ev
                                       al("seek\040D
           ATA,0,                  0;");foreach(1..3)
       {;}my               @camel1hump;my$camel;
  my$Camel  ;while(             ){$_=sprintf("%-6
9s",$_);my@dromedary           1=split(//);if(defined($
_=)){@camel1hum        p=split(//);}while(@dromeda

        t(@dromedary1    ))&&/\S/){$camel1hump+=1<<$CAMEL;}
