Anyway, if you're doing arithmetic on enums you're doing it wrong.  — Sent from Mailbox

nicer repr" is worth "Sorry, I broke your tests, made your published examples out of date, and slowed down your code." While the first two considerations are always potentially applicable when using enums, the latter should only be true for code that uses str() and repr() a lot. For other operations, int-based enums shouldn't add any more overhead than namedtuple does for tuples. I agree with basically everything you said, but I don't want "enums are slower than normal integers" to become a meme - there really shouldn't be a speed difference for any arithmetic operations when using IntEnum.
