The problem is that there are usually strong objections against introducing new warnings. That's because p5p is partly dominated by perl gurus who have used every weird feature in their code at least once, and don't want it to break, or emit a warning.

The second reason to reject warnings usually is "that belongs in a lint utility like Perl::Critic.

A third possible reason can be that some stuff is surprisingly hard to implement in perl5 because it doesn't keep a parse tree of the whole program, but discards the current part of the parse tree as soon as it can be turned into an op tree. Which makes static analysis non-trivial, in some cases (I don't know how it is in this case, though).

Currently I think that a warning is not a bad idea.
