I agree, so I'm sending a patch that does exactly this.
If the enum does not have duplicated values, all remains the same (the
"values" attribute is a dict of value=>enum_type).
If it has duplicated values, the duplicated values point to a tuple of
enum_types in the values attr dict.

 - Maybe I should use lists instead of tuples to avoid the list <=>
tuple conversion
 - I did not use tuples for all entries in the values attribute to
keep the source compatibility.

If this patch get accepted, is there any chance to include it in the
1.38.0 release?
