You should upload it. The ratio of Perl users in the world to regularly participating monks is extremely high. Some feel the CPAN is overcrowded and authors don’t practice enough restraint in uploading every little thing. I’m not one of those. UPLOAD ALL THE THINGS! Just please keep it on github or bitbucket or someplace and include the repository info in your release so if there is interest, you can get quick/easy patches and feedback.

Update: You know, the OP has 21+ right now. That’s a fair indicator of interest.
