If you don't like the current warnings then you could probably help out by supplying the code to make print warn on all those cases.

Believe me, I've tried to make the warnings more sane. I've send in patches. More than once. I've also tried to make remove the warning in its entirely. But if P5P wants to keep the warning as it, how am I supposed to do that?

BTW, I think perl should print the warning in none of those cases, as all cases I gave there's no error. Although it wouldn't be hard to create some cases where there is an error, but no warning is given.
