[capi-sig] Does Py_False or Py_True need de-referencing if used in a PyObject_Compare?

They are like any other object, i.e. they need reference counting.

That's a different case. As long as you are sure that someone (better you)
owns a reference to the object that you pass as argument, you don't need to
increase its refcount just for the call. That's easy to get wrong, though.

Why should it?

I keep being surprised by what some people take their fun in programming
from. Good to see that you're getting actual functionality done regardless.
