I did not know that you had an interest in optimizing vector and matrix operations. Awesome!
We definitely want to take a look at synergies. These low level things are needed for Bloc, but they definitely do not have to be in Bloc.

In the next few years, I think we will improve the performance of those vectors/matrix library using the processor vector instructions, and it would be nice if we have to improve one but not two libraries of vectors and matrix (This is the polie way of saying I am going to improve one library and the others will have to do it themselves).
