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