While creating class of List and using a Optional as part of the typing system. I have got an error when I was importing one of my module. I was able to simplify the problem by creating a one module that replicate the crash. |

Ow, that's bad. :-( Great job reducing this to a minimal repro! I'm guessing it's got to do with registration. I'll try to figure out how to fix it; the fix should appear in Python 3.5.2. |

Simpler repro:
from collections import UserList
from typing import Sequence
class MyList(UserList, Sequence):
pass
isinstance(None, Sequence)
No progress yet in understanding. :-(

See also https://github.com/python/mypy/issues/1546 -- possibly it's the same issue. |

Actually, see https://github.com/python/typing/issues/222 instead. |
