Not to disagree with your plan, but CPAN and modules -- or even just core modules; the ones installed with your Perl -- are so nearly intrinsic to programming with Perl, that you won't be well served by postponing your use of them too long.

And beyond their utility for your production needs, reading a module (pick some!) and its documentation can be really enlightening/educational.

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
