How about a naming convention instead, where using a leading underscore in a parameter name is a hint that it is positional-only. For example, the docstring of sorted: sorted(iterable, key=None, reverse=False) --> new sorted list would become: sorted(iterable, key=None, reverse=False) --> new sorted list In any case, boy am I -1 on this. If you wish to continue this proposal further please write your own PEP.

A leading underscore indicates a private implementation detail. The proposed signature now looks like we can provide a key and reverse, but only riskily provide the actual thing we want sorted. No warm fuzzy feelings there! ;)
