This is excellent news.

BTW, what namespace it will use? std.????

 From a purely marketing / promotional perspective, may I suggest 
numD?

People will immediately recognize numPy => numD, and if we can 
even make the interface the same, people may adopt it more 
quickly. I know there is numir project, but there are several 
repos under https://github.com/libmir, as a user I sometimes got 
confused which one to use, can they *all* be merged into a single 
library numD?
