To the best of my knowledge a hash key will always evaluate to at least undef.

You keep using key when you're talking about the value. Either way, I never said otherwise.

0 and "0" I believe will wind up being in practice the same thing.

They are different although usually interchangeable. And then there's "0.0". It's true while equal to zero. That's why it's important to list "0"
