I remain -1 on forcing "Python syntax" to support all of these odd corner cases (and positional-only is already a corner case, range/addch are seriously so). Considering the prevalence of positional-only functions and methods, I don't think they can be called a corner-case. (Or maybe I've just had the bad luck to run into all of the few there are.)

You're probably right - I was exaggerating, sorry. I do however consider most positional-only arguments in builtins to be an implementation artifact - if they could have been positional-or-keyword when they were introduced, they may well have have been (keyword args in C were a later addition to the C API, I can't recall exactly when but a good chunk of the existing builtins were already there when they arrived).
