+ *
+ * Date:    23 October 2003
+ * SUMMARY: Unescaped, unbalanced parens in a regexp should cause SyntaxError.
+ *
+ * The same would also be true for unescaped, unbalanced brackets or braces
+ * if we followed the ECMA-262 Ed. 3 spec on this. But it was decided for
+ * backward compatibility reasons to follow Perl 5, which permits
+ *
+ * 1. an unescaped, unbalanced right bracket ]
+ * 2. an unescaped, unbalanced left brace    {
+ * 3. an unescaped, unbalanced right brace   }
+ *
+ * If any of these should occur, Perl treats each as a literal
+ * character.  Therefore we permit all three of these cases, even
+ * though not ECMA-compliant.  Note Perl errors on an unescaped,
+ * unbalanced left bracket; so will we.
+ *
+ * See http://bugzilla.mozilla.org/show_bug.cgi?id=223273
