What's `RE`? Do you mean the enums in the re module, `re.I` etc?

How does that work? If I do this:
class MyEnum(Enum):
RED = 'red'
RED = MyEnum.RED
is that a global constant or a non-global constant? How do I hook into
whatever magic is used to decide one way or the other?

It's not clear to me what the change actually is. You explained what the
behaviour is being changed to but not what it is being changed from.
My quick tests are inconclusive:
re.I has repr and str both return 're.IGNORECASE'. Will that change?
MyEnum.RED above has repr "<MyEnum.RED: 'red'>" and str 'MyEnum.RED'.
Presumably that will change to 'MyEnum.RED' and 'RED' respectively.
