  It would be a wasted gethash call, but otherwise no different at all.
  So I am not sure what you think would be so different.

  Nothing would happen to these keys, and the case would do exactly the
  same as without my code.

  If you did not specifically refer to my code but replied to my article,

  appear to is normal on USENET, but it is still a little confusing.
