For what it's worth, __LHS__ seems best to me, of the suggestions so far.
The fact that it's all caps suggests even more magic than most dunders.

To recap the problems this might solve:
1. pass identifier as string arg (seems trivial, status quo is fine)
2. get name and qualname for pickling (instead of sys._getframe)
3. @public for constants (as per Barry's email)

I don't know what that last one was referring to. Do you mind clarifying,
Barry (or anyone else)?

Any other problems this could help with?
