[issue33395] TypeError: unhashable type: 'instancemethod'

having a tough time trying to reproduce this issue in pure python.

any clue as to how to create a __repr__ that's unhashable?

class UnhashableRepr(dict):
    __repr__ = _testcapi.instancemethod(dict.__repr__)

doesn't work because that turns into a <slot wrapper '__repr__' of 'dict' objects> which becomes hashable.

i'd love to provide a patch, seems trivial to fix, but wouldn't want to do so without some tests.
