Takes input in the form of a list with one word on a line then finds then prints all of the anagrams. I originally wrote this on a challenge from a co-worker. When I gave him a solution in under 5 minutes, he gained a lot of respect for Perl.
#! /usr/bin/perl -w
use strict;
my @words = <>;
chomp(@words);
&find_anagrams(@words);

# Takes a list or words, finds all anagrams in it
sub find_anagrams {
  my %anagrams;
  foreach my $word (@_) {
    my $key = join '', sort(split(//, lc($word)));
    push @{$anagrams{$key}}, $word;
  }
  foreach my $lst (values %anagrams) {
    if (1 < @$lst) {
      print "@$lst\n";
    }
  }
}
