Fair enough. 

BTW, about bind, I haven't really looked into it all,
but how 'complex' is it going to be? Consider the 
following example:

class C {
public:
    void Func(int,int,int);
};

int main()
{
    C c;
    boost::function<void,int,int> f;
    f = boost::bind<1>(&C::Func,c,100);
    f(1,2); // will call C::Func(1,100,2)
}

Can bind do this or similar or is it too much?
