| 21 * Misusing the {DecmalDigits} quantifier - according to ECMA, | |

| 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. | |

| 34 * a SyntaxError. Note we use checkThis() instead of testThis(). | |
