There is a difference between warnings and errors; and treating them both the same is like treating gangrene and a paper cut equally with amputation.

It's worse than that. p5p is cautious about adding exceptions for previously working code, at least without requiring users to use the feature pragma or an explicit version number. p5p is much more willing to add warnings where they did not exist before.

Code which unilaterally converts warnings to exceptions could find itself dying of exceptions when run on a new release of Perl, whereas code which enables warnings would (merely) add to the warning logs. That's a risk I'm not willing to take for most code.

Edit to add: I know BuK already knows everything I wrote, but his message was the best place to put this reminder for everyone else.
