Try using Go for any serious math project, then do the same using Julia. Report back as to how both approaches went :P. From someone who uses both languages for very different tasks regularly, I would never try to write Torch from scratch in Go. I can't envision a way for it not to be a serious maintenance or performance disaster. Maybe that's a lack of my own creativity, but I'd much sooner use C++ rather then write any large portion of it in Go. If only for template generics...
