I explicitly mentioned Gogland (the Jetbrains IDE). I'm not a fan of heavyweight editors (including emacs), and I'd gladly just use vim for Go if vim-go had refactoring support beyond the useless gorename. Gofmt works nicely across the board, but godef needs your entire package to compile as far as I remember. Neither of them gives you refactoring support, and gorename doesn't give you much either. You seem to think godef/gofmt is enough which is fine, but in this case Scala has the same level of support as Go.
