My son works at a company where they analyze source code and report on potential data privacy violations. For this they need to parse source code in various programming languages. He mentioned that one day they might need to support Perl too. I thought about the difficulties in parsing Perl and one case came to my mind was the strange implicit return from a function that Perl has.
Anyway, back to Perl:
I recommend always turning warnings on from the beginning of each Perl file.
However sometime we might want to avoid some warnings. We can selectively turn off warnings inside lexical scopes, that is, till the end of the current pair of curly braces.
While Perl developers who upload their code to CPAN will greatly benefit from the volunteers behind CPAN Testers setting up a CI system has a number of benefits even for CPAN developers.
