title: simpler Powershell OR condition syntax
body: <p>Is there a simpler way to specify an <code>-or</code> condition? For example, <code>if ($returnValue -eq 0 -or $returnValue -eq 5)</code>. I would rather write something like <code>if ($returnValue -eq 0 -or 5)</code> to test two possible values of $returnValue. Of course that's doing something else. 
  Ok, just thought of coercing the value into a character type using a regular expression:
  <code>if ($returnValue -match '0|5')</code>
  So, now that I've answered my question, any other ideas?</p>
