I gave a glance to oven library

rng|columns(5, 7)|at(5)    really a nice construct !

However I think that Neal wants to start with something like a vector<  
vector<int> > and I didn't succeed in guessing if your library can manage  
it.

Do you foresee to submit oven for a boost review sooner or later ?
