[Python-Dev] Enum, Flag, contains, and False vs TypeError (original) (raw)

I expect that for IntFlag x in flags is equivalent either to

 bool(x | flags.value)

or to

 (x | flags.value) == x

It should return some result only if x is an integer (or compatible with integers) and raise a TypeError otherwise.

Don't add any special checks unless there are good reasons for this. Keep the code as simple as possible.
