Last week I took part in a pair programming event put on by the local Perl Mongers as hosted by our own TomDLux. It was most illuminating, but what really fascinated me was the use of h2xs to build the framework for the module that we were writing.

Any one who is serious about learning about how modules work or has any interest in downloading and using modules from CPAN should definitely use h2xs to build a module (if they haven't already). Once you've built a module (and written a few tests), gotten everything to pass and written some documentation, the whole black art of using modules should be much clearer.

That was the approach the man behind the keyboard took (I kibitzed from the side), and it was facinating to watch. Needles to say, I learned a huge amount. Highly recommended.
