     21 * Misusing the {DecmalDigits} quantifier - according to ECMA,
     22 * but not according to Perl.
     23 *
     24 * ECMA-262 Edition 3 prohibits the use of unescaped braces in
     25 * regexp patterns, unless they form part of a quantifier.
     26 *
     27 * Hovever, Perl does not prohibit this. If not used as part
     28 * of a quantifer, Perl treats braces literally.
     29 *
     30 * We decided to follow Perl on this for backward compatibility.
     31 * See http://bugzilla.mozilla.org/show_bug.cgi?id=190685.
     32 *
     33 * Therefore NONE of the following ECMA violations should generate
     34 * a SyntaxError. Note we use checkThis() instead of testThis().
