Following the comments in python ideas [1], I'm submitting a bug report. In python 3, dictionary views (KeysView and ItemsView specifically) do not adhere to the same interface as Sets. Specifically, the __and__, __or__, __xor__, and __sub__ methods on Views will accept a non-set type (`{}.keys() | []`), while the same throws a TypeError on a Set. The suggested, not-backwards-compatible solution, was to have dictviews raise errors in the same way.
