Pardon my ignorance (I don't know much about the perl internals) but I was under the impression that there was something like boolean context. So shouldn't the hash in if (%hash) {} be able to tell that it was used in boolean context and thus react accordingly? This should then be an easy patch, just defining a different behaviour for %hash in boolean (in contrast to scalar) context.
