That still needs to be done for PyObjectGCxyz. "Shall not mix", "shall hold the GIL", "guaranteed binary compatibility",

[Neil, the PyObject_GC Master]

Yes.

"shall not use in contexts requiring function designators"

People need some form of GC free to initialize tpfree. Extensions can't really use PyObjectGCDel, can they?

No they can't. So we promise that PyObject_GC_Del can be used in contexts requiring function designators. We're sure that PyObject_GC_{New, NewVar, Resize} can't, since they cast their results to a type "passed" as an argument.

Harmonic convergence?
