By the way, PyObject_CallFunction("O") has a surprising behavior: if you pass a tuple, the tuple is unpacked, whereas any other type is passed directly. See bpo-28977.

I would prefer to fix the API since it caused severe bugs in the past, like asyncio generator bug bpo-21209.

But I'm not sure if we can do it without a deprecation period... I'm not sure that we should deprecate anything, since I would expect that PyObject_CallFunction(func, "O", tuple) calls func(tuple) rather than func(*tuple)...
