I think there is a conflict of interest with what people want. 
There seem to be people like me who only want or need simple 
matrices like glm to do basic geometric/graphics related stuff. 
Then there is the group of people who want large 500x500 matrices 
to do weird crazy maths stuff. Maybe they should be kept 
separate? In which case then we are really talking about adding 
two different things. Maybe have a std.math.matrix and a std.blas?
