2. We restore __getitem__ on EnumMetaclass *solely* for member lookup by name (the "getmember" functionality above). This would leave __call__ used for the reverse lookup (value to member and hence name) and __getitem__ for the forward lookup (name to member and hence value) (Note: given Ethan's comments about his current implementation, I believe this actually fits nicely with the way EnumMetaclass.__getattr__ is already implemented)
This has the advantage of leaving one obvious way to do the 'reverse' lookup (namely __call__), rather than two redundant alternatives. Cheers, Phil
