      Implement typing.assert_type as proposed in https://mail.python.org/archives/list/[email protected]/thread/MITFQ6Z45RRMXY3HNM66IC3XXS3TA3JN/. This is a special primitive that asserts to the type checker what the type of an expression is.

      Tentatively dropping assert_error() based on Eric's feedback.
