The following typescript program is accepted:

class C {
    static length ()  { return "twelve"; }
}

However, in the generated code:

var C = (function () {
    function C() {
    }
    C.length = function () {
        return "twelve";
    };
    return C;
})();

Here, an attempt is made to assign to the length property of a function. This doesn't work (at least in Firefox and Chrome), causing subsequent calls of C.length() to crash. Perhaps calling a static class function length should just be disallowed?
