automatic casts

[Arne Goedeke]

I am wondering how hard it would be to implement automatic casts from 
objects to basic types. You probably know what I mean... small example:

    void fun(int a) {
            ...
    }
    object i = Int(32); // Class offering a cast method

    fun(i); // cast to int automatically

I admit that it introduces new traps and some complexity. Any opinions?
