It's a small refactoring. Lurking at collections.abc I found a lot of: >>> any(attr in B.__dict__ for B in C.__mro__) also repeated in typing.py of mypy: https://github.com/JukkaL/mypy/blob/master/lib-typing/3.2/typing.py#L117 It seems to be a common operation to check or get an attribute from mro in abc, so I thought it could help to have dedicated functions to enhance readability. (see patch e.g. Hash.__subclasshook__ takes 1 line intead of 7...)
