Use of .apply() with 'new' operator. Is this possible?

Question

In JavaScript, I want to create an object instance (via the new operator), but pass an arbitrary number of arguments to the constructor. Is this possible?

Answer 1

function createSomething() {
    var args = Array.prototype.concat.apply([null], arguments);
    return new (Function.prototype.bind.apply(Something, args));
}

If your target browser doesn't support ECMAScript 5 Function.prototype.bind, the code won't work. It is not very likely though, see compatibilty table.
