"__hash__ = None" in a cdef class should disable hashability #984

Open robertwb opened 10 years ago

robertwb commented 10 years ago 
cdef class MyType(HashableBaseClass):
    __hash__ = None

should set

MyType.tp_hash = PyObject_HashNotImplemented

to disable inheritance of the base type's tp_hash slot.
