+// Don't allow malformed unicode escape sequences in identifiers.
+// In strings and regexps we currently allow malformed unicode escape
+// sequences without throwing a SyntaxError. Instead "\u22gk" would
+// treat the "\u" as an identity escape, and evaluate to "u22gk".
+// Due to code sharing, we did the same in identifiers. This should
+// no longer be the case.
