equal? - the predicate which reports whether values are structurally identical.

equal?! - the operator which really expects values to be identical,
and raises exception exn:fail:huh?! when they aren't.

equal! - the operator which fixes values to BE structurally identical.

equal. - the operator which mimics equal!, but doesn't get so excited about it.
