> scientific computing

for quite some time, and I've the value of a REPL steadily in decline: what's far more useful is a tested code snippet or function & a debugger, occasionally.

Also, if a scientific stack were available in Go, I'd jump on it, because deploying Go is so much simpler than Python. Python's deployment story for scientific software often starts with either )a) create the perfect storm of dependency versions or (b) use Anaconda. Even MATLAB is way better in this regard.
