Hi all, I have a slight variant of the decorator proposal. Rather than specify a count, let the decorator implement the typeshed dunder convention: @positional_only def replace(self, __old, __new, count=-1): (I imagine this decorator would also treat "self" as position_only, so no need for __self.) Pros: 1. Consistent with the typeshed convention. 2. Avoids a count. 3. Strictly opt-in, so hopefully keeps those @#?! underscore preservationists from picketing my lawn (again!).

I like the idea, but I wanted to note that since it has no meaning from the point of view of the defined function, it can be done with a magic decorator, so new syntax is not required:
@positional_only[:4] def replace(self, old, new, count=-1): ...
I"m confused, what does the [:4] mean?
if you want old and new to be positional only, wouldn't it be something like:
@positional_only(3) def replace(self, old, new, count=-1): ...
i.e. the first three parameters are positional only.
and why indexing/slice syntax???
+! on the idea -- still on the fence about syntax.
