How could Go possibly be anything but a inappropriate choice? For numerics and working with data, Go would be about as expressive as Fortran or C, but slower. I took a quick look at Gonum, it's highly imperative and monomorphic just like Fortran. It makes me sad that these efforts could be spent improving the ecosystems of Haskell/OCaml/F#/Scala. These languages are far more expressive than Go and offer far more type-safety, all with the succinctness of Python
