* 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().
