Oh right. I hate primitive types. Everywhere in my code I have to say: typeof x == 'string' || x instanceof String
Will this get any better in es4? I seem to recall that Dylan somehow kept Number open but sealed Integer and Float so you could have competitive numeric performance and still permit a user throwing in a Complex library. Couldn't string be a sealed subclass of String so I can be generic if I use String, or I can restrict myself to string and be fast?
