Then we have O(1) lookup using decltype:
template
    struct at
    {
        typedef decltype(Vector::item_(Index())) type;
    };
I haven't tested this code yet, but the Boost.MPL works in a similiar way
for compilers that suppor typeof. Of course generating the `item_` overloads
[...]

That's how the map is currently implemented, but I don't use the preprocessor
to generate overloads.

See the top of [1] for details, it's pretty simple.
