Argument clinic: outdated tutorial

Documentation

The tutorial for Argument Clinic in the devguide contains an outdated section. It still describes the early implementation that used to generate calls to PyArg_ParseTuple*() functions. This is no longer the case.

The affected section starts with "First, ensure both places use the same argument-parsing function." and goes for a few paragraphs until "If any of these items differ in any way, adjust your Argument Clinic function specification and rerun Tools/clinic/clinic.py until they are the same."

Given that the output is now very different, this is quite confusing to read. The section probably needs to be completely rewritten.

Apri il tutorial di Argument Clinic collegato e rivedi la sezione che inizia con «First, ensure both places use the same argument-parsing function.». Confronta le sue affermazioni con l’output e il comportamento attuali di Tools/clinic/clinic.py. La documentazione sarà completa quando questa sezione descriverà accuratamente l’implementazione attuale e non presenterà più il workflow obsoleto di PyArg_ParseTuple*().
