Impossible to define static 'length' function on class

[hesselink]

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?

Migrated from codeplex issue #1260.

I ran into this recently. :(

Also a few others are disallowed e.g. the following code should error (if we do this feature):

class C {
    static name = 'something';
    static arguments = 'args';
    static caller = 'caller';
}

console.log(C.name); // 'C'
console.log(C.arguments); // null
console.log(C.caller); // null

Not all of these are stardard however.

I don't think the properties name, caller and length are doable. They are read-only properties and can't be overridden. All assignments to them will be ignored.
