Yes, looks like a bug:
------------------
cdef class B:
pass
cdef class C:
pass
def test_custom_tuple(obj):
"""
>>> test_custom_tuple(A())
True
>>> test_custom_tuple(B())
True
>>> test_custom_tuple(C())
False
"""
return isinstance(obj, (A,B))
------------------
Fails for B(), the second type check is simply dropped.
I'm looking into it.
