I don't think that is a good idea.  We currently put argument default
values in the function signatures in Python syntax, but only because
that also makes sense from a documentation PoV.

We also wouldn't write


just because that's (one) way for creating properties from Python.


(I am -0 on @positional myself: IMO such a completely different way
of declaring positional-only and keyword-only arguments lacks grace.)
