Re: [Gnash] AS Function and C Function

[strk]

I'll expand with an example:

        String.prototype.sayHello = function() { return "hello"; };
        var p = new String();
        trace(p.sayHello());

In the above example String is our "class".
In Gnash, the String constructor (as every other Built-in class
constructor) is a C function:

        struct fn_call;
        typedef void (*as_c_function_ptr)(const fn_call& fn);

So we cannot add properties to them!

I think each built-in class should be an instance
(possibly a singleton) of a function_as_object.

Comments welcome.
