Note that __lcontains__ (if it exists) would be called first, at least for
different types. So maybe it would be easier than you think. But I still

Hm... with only a little bit of cooperation of the container class (e.g.

class xylophone:
def __contains__(self, item):
if hasattr(item, '__lcontains__'):
return item.__lcontains__(self)
return False

import-related PEPs for
