As I was 37,000 feet in the air flying across the country, I need a Perl module to extract information from a cooked template. If I was going to create that module myself, I’d call it Template::Extract.
The Comprehensive Perl Archive Network (CPAN) has so many modules that most things probably already exist. I figure out what I would call the module (and, since I’m a PAUSE admin, that’s often what they are called ;), then try to install it. I just assume it exists.
prompt$ cpan Template::Extract
The CPAN.pm module finds Template::Extract in my minicpan on my laptop (so I can install modules while on an airplane) and starts to install it, and it’s exactly what I want.
This happens quite a bit, actually, and I still think this is one of the reasons that Perl is popular. I’d be really nervous about Ruby and Python if they had the same thing (and I think they will, eventually).
