Carter claims he can perform optimizations that aren't possible in other languages, though I can't personally speak to them since I'm not well versed in numerical code.
It's not yet in shape for general use, nor for being advocated. There is some tech there that's unique in terms of handing matrix computation on rich formats nicely.
I'd prefer if we reserve advocacy for when i get it to the point where there's public documentation, or at least examples :)
