There were many times when I PROVED that something can't be done, and then
actualy did it... Or somebody else did it. :o))

Boost tuples allow the access by the position number. To access by name,
we would have to somehow map the name to the position number. We would
probably have to use strings to define names, which would elliminate the
posibility of compile time checks. Also, static_cast should be
significantly faster than iterating through boost::tuple fields.

I think our approach, which is just a simplified version of Andrey
Alexandrescu's GenScatterredHierarchy, fits rather nicely here...
