[New-bugs-announce] [issue22507] PyType_IsSubtype doesn't call __subclasscheck__

[Maries Ionel Cristian]

New submission from Maries Ionel Cristian:

It appears it just does a reference check: https://hg.python.org/cpython/file/3.4/Objects/typeobject.c#l1300

It appears it's the same in 2.7: https://hg.python.org/cpython/file/2.7/Objects/typeobject.c#l1161

But this is not the intended behaviour right?
