I don't have a good one in mind - though

I don't think that would work - but reasoning about MRO hurts my brain ;-)
You'd have to declare the class like this:
class FileIO(io.FileIO, IOBase):
pass
to get the io.File methods to resolve first. But that means that the
method invocation chain would be broken by io.IOBase, which doesn't make
super calls.
Cheers,
