>> It could be great. But I afraid this may add too much complexity in C code. Maybe try to implement a simple and fast Enum for using it in the stdlib and extend it with a richer interface in the enum module?

Personally speaking, I want speedup module for `re.compile` than enum. In case of enum, I feel CONSTANT = "magic" is enough for most cases. re doesn't have such workaround, and using third party regular expression library has very high bar, especially when using it in stdlib. But there were some -1 on adding speedup module for re. I think it's same to enum. So I think we should: * Don't use enum blindly; use it only when it's very far better than CONST = "magic". * Add faster API which bypass some slow part, especially for IntEnum.convert() or IntFlag.convert() in socket module.
