I think the point is that it would create a very mysterious
potential failure mode. What would you make of a situation
where Python says "TypeError: Keyword dict contains non-string
keys", but upon examination, the dict clearly does not contain
any such thing?
No, if the dictionary is not marked as an all-string dict it can
fallback to checking. The common case (dict marked as all strings) is fast.
