New submission from Michael J. Sullivan :
class A:
def foo(self, cls): return 1
class B: pass
class B:
bar = classmethod(A().foo)
B.bar()
In Python 3.8 and prior, this worked. Since Python 3.9, it produces "TypeError:
A.foo() missing 1 required positional argument: 'cls
Michael J. Sullivan added the comment:
I believe that this is orthogonal to PEP 590.
PyObject_CallMethodObjArgs and friends take varargs which need to be copied
into an array one way or another. It is easy (and efficient) to prepend the
base while copying the function arguments

New submission from Michael J. Sullivan :
The different varieties of PyObject_CallMethod* routines all operate by doing a
PyObject_GetAttr to fetch an object to call. It seems likely to be worthwhile
to take advantage of the LOAD_METHOD optimization that avoids creating a bound
method object
Michael J. Sullivan added the comment:
I think this is done!
