- Point at the body expression of the match arm with the type error. - Point at the prior match arms explicitely stating the evaluated type. - Point at the entire match expr in a secondary span, instead of primary. - For type errors in the first match arm, the cause is outside of the match, treat as implicit block error to give a more appropriate error.
