title: Check for multiple values when using comparison operators
body: <p>I've always been under the impression that for any comparison statement, i.e. <code>X == Y</code> or <code>X != Y</code> is the format, and you chain statements together with <code>&amp;&amp;</code> or <code>||</code>. </p>
  
  <p>Is there not some way to write <code>X == (Y || Z)</code> instead of <code>X == Y || X == Z</code>?</p>
  
  <p><strong>Edit</strong>: Since it has been established that this is not possible to do cleanly, how else could it be done?</p>
