[New-bugs-announce] [issue36922] Implement Py_TPFLAGS_METHOD_DESCRIPTOR

[Jeroen Demeyer]

New submission from Jeroen Demeyer <J.Demeyer at UGent.be>:

The new flag Py_TPFLAGS_METHOD_DESCRIPTOR proposed in PEP 590 is meant for classes whose instances behave like unbound methods. In other words, it's meant for objects supporting the LOAD_METHOD optimization. There are two such classes in CPython: function and method_descriptor. But the goal is to enable more such classes.

This is independent from the rest of PEP 590 so let's implement it separately.
