docs: // NewScanStringsHandler returns a ReplyHandler which will convert the reply to
  // a slice of strings and set the value of strings to the converted value. The
  // returned ReplyHandler will grow or shrink strings as needed. The ReplyHandler
  // will return an error if there was a problem converting the reply.
