// +build go1.9

// switch from using go/build to golang.org/x/tools/go/packages. But that
// package depends on changes to go/types that were introduced in Go 1.9. Since
// modules weren't introduced until Go 1.11, using
// golang.org/x/tools/go/packages can safely be restricted to users of Go 1.9
// or above.
