+  { name: 'Superman', costumeColor: 'blue', hasCape: true },
+  { name: 'Wonder Woman', costumeColor: 'blue' },
+]
+
+const predicate = CM.parse('costumeColor:blue hasCape?').createPredicate()
+
+characters.filter(predicate)
+// [
+//   { name: 'Superman', costumeColor: 'blue', hasCape: true },
+// ]
+
+new CM.String('foo').createPredicate()
+```
