When creating a repl there are two Go's, and it's hard to know which one I am creating with because they both display with the name "Go". The Go Beta one seems to work much better as it supports sub packages and Go modules properly.

Could the old Go one be removed, or renamed to indicate it is out-of-date or the old one?
