IISC that may lead to some unexpected UI stuff (community/community#15452, actions/runner#2347), but whatever …

Regarding repr, format and str: I think I've changed my perspective a bit by now. Consider the following example

def pprint(arg: int | str) -> str:
    return "Value is" + str(arg)  # explicitly cast in case it's an int

Now pprint(ChatType.PRIVATE) would yield "Value is ChatType.PRIVATE" which I'd argue is unexpected. So I'm now leaning towards having StringEnum == str.__str__. As no user has complained about that so far, I'm also okay with keeping it as is.

In any case

• StringEnum and IntEnum should behave the same
• repr should give unambiguous output and hence ChatType.PRIVATE is still derisable here IMO
