I don’t see this mentioned in the thread: This “assignment-with-missing-rhs” could generalize to other assignments.
In particular one case where one see same kind of repetition as in kwargs and some syntactic suger maybe could help is:
def __init__(self, height, width): self.height = self.width =
(although I think it looks kind odd and like someone forgot to finish writing that code. Also, dataclasses)
