Wow it looks indeed very interesting. Yes, I know what you mean by "rare
free time". Same thing here :-)
Let me have a more thorough look at it and why not start using it too.
Have you compared it to what is done with Eigen and Armadillo. It seems
these 2 libraries are quite popular these days.
Best,
David
