When in doubt if a Perl related subject fits into SOPW, I normally choose Meditations.

I've seen several meta discussions surrounding modules there before.

Anyway nothing Perl related is off topic here. :)

Edit

Quote: (emphasize added)

Meditations is sometimes used as a sounding-board — a place to post initial drafts of perl tutorials, code modules, book reviews, articles, quizzes, etc. — so that the author can benefit from the collective insight of the monks before publishing the finished item to its proper place (be it Tutorials, Cool Uses for Perl, Reviews, or whatever). If you do this, it is generally considered appropriate to prefix your node title with "RFC:" (for "request for comments").
