The one that gets me presently is "return" statement with explicit "undef" at line 942, column 5. See page 199 of PBP
. I'd like to know when being explicit has ever been a problem. I'm almost tempted to buy that book just to see what the argument is on page 199. Almost.
Update: Ahh, I see... I hadn't thought about list context since the function only ever returns scalars and the results are all checked with if defined $scalar_name. I'm going to go ahead and stick with return undef if $something for functions that only return scalars and consider the advice given by Perl::Critic to be educated guesses or tips.
