code: func equalStr(b *[]byte, s string) bool {
  	return *(*string)(unsafe.Pointer(b)) == s
  }
docs: //
  // The reason for using *[]byte rather than []byte in parameters is an optimization. As of Go 1.6,
  // the compiler cannot perfectly inline the function when using a non-pointer slice. That is,
  // the non-pointer []byte parameter version is slower than if its function body is manually
  // inlined, whereas the pointer []byte version is equally fast to the manually inlined
  // version. Instruction count in assembly taken from "go tool compile" confirms this difference.
