code: func MustParse(s string) UUID {
  	uuid, err := Parse(s)
  	if err != nil {
  		panic(`uuid: Parse(` + s + `): ` + err.Error())
  	}
  	return uuid
  }
docs: // MustParse is like Parse but panics if the string cannot be parsed.
  // It simplifies safe initialization of global variables holding compiled UUIDs.
