Notes:
    Our first real usage of the bindings doesn't look too different from what it
    would look like in C.
    
    In Ruby all variables are pointers to objects, and there's no concept of
    pointer to variables, so what in C looks like "ret1 = func(var, &ret2)", in
    Ruby looks like "ret1, ret2 = func(var)".
