Go ships with a Go parser in the standard library. Among other things it is used by gofix, gofmt and go vet. People from the community have used it for writing various refactoring tools. It's incredibly useful; I don't want to go back to a language that doesn't ship with a parser in the standard library. I'd say the Go authors have thought about support for tooling much more than other language authors, not less.
