A few years ago, I learnt that a name day is a religious event celebrated by Roman Catholics and inherited by their sub-classes. This module attempts to list the names associated with dates, for a number of European countries. Could be quite handy for interacting with those of such persuasions.
But 1/5 for Documentation: very lazy to put it on CPAN with the Usage section reading simply "TODO". And since the author is presumably not able to produce sub-classes for every nation's name-spellings, it might be a good idea to include a section of sub-classing.
Very good, intuitive user interface. Some features are still missing, like handling of multiple religions within a country.
Missing info from documentation about language module setup (a tutorial would be fine).
