I guess that's not really proof, because it could be the
case that the 'join' operator treats hashes differently than
it treats arrays. But I'm fairly certain that the only two
contexts that Perl functions treat differently are scalar
and array context. Everything else is one of those two: a
reference is a scalar, a hash is an array, I'm pretty sure a
filehandle is a scalar, etc.
