Example of using an empty interface to work around the type system in Go

typesEmptyInterface.go

// X needs anything
func X(anything interface{}) {
  // Nothing comes for free - need to see what I got
  switch value := anything.(type) {
  case string:
      fmt.Printf("I got a string!: %s", value)
  default:
      fmt.Print("I got... something!")
  }
}

func main() {
  X("meep")
}
