Description

I would expect these two lines to raise the same set of messages. We don't use inference to analyze whether **kwargs contains the missing named parameter x. We could.

import copy
import os

copy.copy(**{"y": os.environ})  # [unexpected-keyword-arg]
copy.copy(y=os.environ)  # [no-value-for-parameter, unexpected-keyword-arg]

False negative for no-value-for-parameter.
