The requirement of "new" to create new js objects is an unnecessary piece of the language, in fact the need to use it disappears in ES5 as it's no longer the only way to create new objects with a set prototype. There's nothing strange about having a $ function and creating an object from it, in fact it's closer to real prototype-based programming than the `new Class` you see inside of JavaScript.
