Convert the remaining easily convertible functions and methods to Argument Clinic, so that they have a signature for introspection and use a faster calling convention:

  • builtins dir() and vars()
  • property.__set_name__()
  • memoryview.__exit__()
  • structseq __replace__()
  • types.SimpleNamespace.__replace__()
  • re.Match.group()
  • sys.getsizeof() and sys.set_asyncgen_hooks()
  • atexit.register()
  • the os.scandir() iterator __exit__()
  • the _dbm, _gdbm and _decimal context manager __exit__()
  • _functools lru_cache __copy__() and __deepcopy__()
  • _elementtree.SubElement()
  • _interpreters.new_config()
  • _tkinter call() and wantobjects()
  • zoneinfo.ZoneInfo.__init_subclass__()
  • internal hamt and stdprinter methods
  • Issue: Use Argument Clinic for more functions and methods #155496

Sorry, something went wrong.

Uh oh!
