Hi Steven,

I don't manage to get it to work, am I missing something? 
I get a "no matching function call" (gcc 4.7.2).

BOOST_TYPE_ERASURE_MEMBER((n1)(has_foo), foo);

struct Data{};

struct Test
{
    void foo(Data&&)const
    {
        std::cout << "foo(Data&&) called" << std::endl;
    }
    void foo(int,double)const
    {
        std::cout << "foo(int,double) called" << std::endl;
    }
};

int main()
{
    Test t;
    any<
        mpl::vector<
            n1::has_foo<void(Data&&),const _self>,
            n1::has_foo<void(int, double),const _self>,
            copy_constructible<>
        >
            > x (t);
    //x.foo(Data()); // ===> this will not compile
    x.foo(1,1.0); // calls foo(int, double)
    return 0;
}

Thanks,
Christophe
