It seems like a PEP is needed. I followed the threads mentioned above, which led me to PEP 457: https://www.python.org/dev/peps/pep-0457/ I didn't find a clear indication if it was still to be modified, approved or rejected. Can anyone help?
Effectively deferred, since Guido decided we didn't need a PEP for the text_signature syntax in the inspect module:
>>> import inspect
>>> inspect.signature(ord)
<Signature (c, /)>
>>> ord.__text_signature__
'($module, c, /)'(The motivation was to give Argument Clinic a way to communicate C level signatures up to Python code)
A PEP for Python level positional-only argument syntax would be able to rely on Signature.repr and text_signature as precedent for using "/" to indicate that the preceding parameters are positional-only, though.
Cheers, Nick.
