+description: Greedy loop
+info: |
+  The production Assertion :: (?<=Disjunction) evaluates as follows:
+    1. Evaluate Disjunction with -1 as its direction argument to obtain a Matcher m.
+    2. Return an internal Matcher closure that takes two arguments, a State x and a Continuation
+        c, and performs the following steps:
+      a. Let d be a Continuation that always returns its State argument as a successful MatchResult.
+      b. Call m(x, d) and let r be its result.
+      c. If r is failure, return failure.
+      d. Let y be r's State.
+      e. Let cap be y's captures List.
+      f. Let xe be x's endIndex.
+      g. Let z be the State (xe, cap).
+      h. Call c(z) and return its result.
