1.10 + *
1.11 + * Date: 23 October 2003
1.12 + * SUMMARY: Unescaped, unbalanced parens in a regexp should cause SyntaxError.
1.13 + *
1.14 + * The same would also be true for unescaped, unbalanced brackets or braces
1.15 + * if we followed the ECMA-262 Ed. 3 spec on this. But it was decided for
1.16 + * backward compatibility reasons to follow Perl 5, which permits
1.17 + *
1.18 + * 1. an unescaped, unbalanced right bracket ]
1.19 + * 2. an unescaped, unbalanced left brace {
1.20 + * 3. an unescaped, unbalanced right brace }
1.21 + *
1.22 + * If any of these should occur, Perl treats each as a literal
1.23 + * character. Therefore we permit all three of these cases, even
1.24 + * though not ECMA-compliant. Note Perl errors on an unescaped,
1.25 + * unbalanced left bracket; so will we.
1.26 + *
1.27 + * See http://bugzilla.mozilla.org/show_bug.cgi?id=223273
