This lint catches cases where the last statement of a closure expecting an instance of Ord has a trailing semi-colon. It compiles since the closure ends up return () which also implements Ord but causes unexpected results in cases such as sort_by_key. Fixes #5080 reprise: rebase, update and address all concerns
