Consider this program

(Bool/not Bool/true) = Bool/False
(Bool/not Bool/False) = Bool/True

The second rule is not actually reachable because we mispelled True in the first one, so it's taken as a variable pattern.

Users have no indication that this happened even though it's almost always a mistake. We want this to throw a warning instead.
