As far as I know IronPython is the only Python VM that doesn't have _getframe()
support by default (you need a CLI flag at startup, IIRC). In PyPy calling
_getframe (right now) has a negative performance impact, but it's local to
wherever you're calling it, so unless you create Enum in frequent loops (as
opposed to just once at module level), this doesn't really matter to us.
If someone wants to invent a more narrow, tailored API for stack introspection,
logging is a much better target (right now each call to
logging.{info,error,etc.} calls _getframe(), which does have a real performance
impact. (We'll eventually invent enough engineering to fix this ourselves, but
in the meantime if somewhere were to pain this bikeshed, we certainly wouldn't
object ;)).
