/* * * 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 *
