I'm sorry, but I'm losing track as to what precisely you are trying to
say. You seem to be using a mental model that is entirely different
from mine.

But what follows from that point? So it shows some kind of matter...
what does that mean for actual changes to Python API?

What is "that" which might be really feasible? To "solve Walter's
conundrum"? That "signatures make sense"?

So I can't really respond to your message in a meaningful way;
I just let it rest...
