Hi Emily,

When I needed something very much like this in my last job, Aleksey Gurtovoy
wrote some simple tuple metaprogramming extensions that were quite useful to
me. So, that is to say:

1. Yes, other people will be interested
2. You might take a look at Aleksey's work. Some related stuff is on the
"mpl-development" branch in boost/mpl
