[Tuple] Addressing by named tag?

[Robert Jones-2]

Am I correct in believing that tuples have to be accessed by element index,
as in

tuple.get<0>()

Multi-Index container has a really nice facility to use named (well typed
really) tags in these
kind of expressions, but it seems tuples do not.

Anyone fancy adding it to tuple?

What you want already exists in Boost.Fusion. It's a map.
