in reply to Production Environments and "Foreign" Code

I've used a lot of CPAN modules in production code. CPAN is probably the primary reason I use perl for most of my work since it enables me to build quality apps quickly. Not using CPAN is... foolish :-)

The important thing is to have some sort of process. My general rules when using other peoples modules are:

Even if you do all of the above it will still take less time than writing something like DBI or Template from scratch.

I've only very occasionally had problems. Some of the non-upward compatable changes made to Class::DBI being the only ones that ever caused serious hassles - and that was because somebody else ignored the last point above :-/

Hope this helps.
