Go is giving a 1.6.2 repl which is a few years old at this point. Can we get a 1.9 repl please
This has been implemented, see (https://repl.it/languages/go)
For repl.it developers updating go: this link might be useful https://blog.golang.org/playground it explains how the golang online playgorund is built
Yes this is sad to see, needs updating! Lots of go users out there!
go is updated every 6 months - 1.10 is out, 11 is next.
