[issue46316] Optimize pathlib.Path.iterdir()

[Barney Gale]

New submission from Barney Gale :

pathlib.Path.iterdir() contains the following code:

if name in {'.', '..'}:
# Yielding a path object for these makes little sense
continue

This check is unnecessary as os.listdir() does not return entries for '.' or 
'..':

os.listdir(path='.')
Return a list containing the names of the entries in the
directory given by path. The list is in arbitrary order, and
does not include the special entries '.' and '..' even if they
are present in the directory

See https://docs.python.org/3/library/os.html#os.listdir
