BTW, (it was probaby already discussed, and I just miss it)
Why couldn't we implement is_convertible like this:
struct convertible
{
    template<typename From>
    struct from
    {
        template<typename To>
        struct to
        {
            enum { value = .... };
        };
    };
};

The usage would be more expressive:
is_convertible::from<Type1>::to<Type2>::value
