With a help of boost::dynamic_any::call operation (not yet implemented) it's
possible to use boost::dynamic_any::any instead of Boost.Function. Though
this new solution is less specialized and probably slower then
Boost.Function it has one advantage demonstrated in the example below:

typedef boost::dynamic_any<
        boost::dynamic_any::call<void (int &)>,
        boost::dynamic_any::call<void (double &)>
> flexible_function; // 2 in 1!

int main()
    flexible_function f;
    f = ++_1; // increment for int and double

    int i = 2;
    f(i); // ++i

    double d = 3;
    f(d); // ++d
