in thread prevent stringification for hash-keys

Heheh yes tobyink I thought about that too, but the OP appears to want to forbid in code the use of a string as a hash key, whether quoted or not, and only allow using a declared variable. IIUC.


The way forward always starts with a minimal test.

    No, he wants to avoid stringification of hash keys, especially of barewords.

        Terminology is a bitch. While it's true that interpreting a bareword as string, which occurs at complile time, is not called stringification, I think it is clear that OP wants $hash{blahblah} treated differently from $hash{'blahblah'} … only the former should be a syntax terror, something like use stricter; .-)
