Absolutely, post your module.  The monks are never shy to give their advice, critique, and opinions.

As for the appropriate section under which to post -- I've seen arguments made for both Meditations and Seekers of Perl Wisdom being good choices.  For my money, the former (Meditations) is slightly better, because you're not asking a specific question, but rather sharing your work, and seeking feedback on it (ie. "request for comments").

So by all means, choose a relevant title, create a writeup describing it, and share it with the group!
