I expect Go would end up like C++ without header files or OCaml without sum types and pattern matching, falling somewhere in between them. Although if errors are handled properly instead of by panic then it might really hurt in the line count from all the `if err != nil { return; }`

Also I commented somewhere else in this thread re perf comparison. Short answer is that since there's no incentive towards performance the signal would be swamped by differences in how much people avoid O(n^2) algorithms even if you don't need to.
