You could check out the weekly cpan ratings[0] for "popular" modules, though I find the best appraoch is to search cpan for modules as I need them. CPAN Modules themselves often serve as a decent template for the form and structure of a Perl application and tests, see the App:: space for standalone applications (e.g. App::cpanminus). If you're returning to Perl (or just starting out) you can do worse than check out Beginning Perl[1] and Modern Perl[2]. There are also Perl distributions such as DWIM Perl[3] which bundle Perl and the most commonly used modules.

Thanks. Seems dwim is more for web apps or servers. And its pretty new. I have downloaded Modern Perl recently and do have a lot of books on perl bought (and read) in the early 2000's. I am wary of generally downloading modules from CPAN since I have already earlier found some to be broken, or have dependencies that are abandoned. Which is why I sort of look for a curated list that is likely to be maintained. I;ve had the same issues with ruby and other languages as well, and am careful of what I depend on. Currently, I've been bitten by ruby's unicode issues (string functions crashing out of the blue in 1.9) and am thus considering going back to perl.

  That hasn't been my experience with CPAN, though cpantesters and cpanratings can serve as a guide to what works and what doesn't. This type of service does not exist for rubygems/pypi to my knowledge. While Perl's unicode support is unparalleled, there are some things to be aware of: http://www.perl.com/pub/2012/04/perlunicook-standard-preamble.html http://www.perl.com/pub/2012/04/perlunicook-standard-preambl...

  A good way to find out if there are issues with a CPAN module is to look at the Test results provided by the CPANtesters smoke testing. For eg. on TryCatch (https://metacpan.org/module/TryCatch https://metacpan.org/module/TryCatch) it currently shows... Test results (1933 / 172 / 1) This means its tests have passed on 1933 different test machines (on various different versions of Perl & OS's). However there have been 172 machines reporting a problem. Clicking on the Test results link delves down deeper - http://www.cpantesters.org/distro/T/TryCatch.html#TryCatch-1.003000 http://www.cpantesters.org/distro/T/TryCatch.html#TryCatch-1... From this I can see there are a lot of failures with this (version of the) module recently. So there is a new problem that's manifested itself recently in a small number of tests - http://www.cpantesters.org/cpan/report/42fb1e6c-749d-11e2-8c23-9ffbde4da9a6 http://www.cpantesters.org/cpan/report/42fb1e6c-749d-11e2-8c... Looking at the test failure (it failed 6 out of 58 tests) I think it was fine to just force installation for now. The module owner will receive an email for everyone of these 172 smoke test failures so I doubt it will be long before he/she fixes this problem :)
