-  (*SKIP)   fail this match attempt, bumpalong to current match point
-  (*THEN)   fail this branch, try next branch at same level or fail if none
-  (*COMMIT) fail this match attempt, suppress bumpalong
-  (*FAIL)   fail and backtrack (same as (?!) and that can be optimized)
-  (*F)      synonym for (*FAIL)
