I am the very package of a Perl 5.6 programmer,
I've information stringable, arrayable and hashable,
I know the Perlish functions from versions historical,
From absolute to transliterate in order categorical.
I'm very well acquainted, too, with matters packageable,
I understand method calls both class and objectifiable.
About regular expressions I'm teeming with a lot of clues,
Of how to change your matching term depending on the brackets used.
I'm very good at golfing, with pack, map, do or for,
And a complicated regex I'll use qr to store.
In short, in matters stringable, arrayable and hashable,
I am the very module of a Perl 5.6 programmer.

If there hasn't been one of these before, I'd be very surprised, but a quick look didn't find it, so here you go. Suggestions welcome.
