[issue17343] Add a version of str.split which returns an iterator

[Martin Winks]

Martin Winks <cat at snejugal.ru> added the comment:

> Perhaps the use case is already served by re.finditer()

def split_whitespace_ascii(s: str):
    return (pt.group(0) for pt in re.finditer(r"[A-Za-z']+", s))

solution above does not cover all possible data and is incorrect for bytes-like objects.

writing regular expressions for different separators/data would be a quite overheadish, so the idea of one-case solution doesn't seem to go very far and requires a bigger change in code for different separators.

let's try to revive this one :)
