+    21.2.2.2 Pattern
+
+    The production Pattern :: Disjunction evaluates as follows:
+
+        1. Evaluate Disjunction to obtain a Matcher m.
+        2. Return an internal closure that takes two arguments, a String str
+           and an integer index, and performs the following steps:
+           1. If Unicode is true, let Input be a List consisting of the
+              sequence of code points of str interpreted as a UTF-16 encoded
+              (6.1.4) Unicode string. Otherwise, let Input be a List consisting
+              of the sequence of code units that are the elements of str. Input
+              will be used throughout the algorithms in 21.2.2. Each element of
+              Input is considered to be a character.
