title: Save more values to one key and still use hash.value?(['something'])
body: <p>I need to save more values with the same key into a hash in Ruby. But I still want to be able to find them with <code>.value?</code>.</p>
  
  <p>If I save array to hash, I can't find a single value.</p>
  
  <p>For example, if I have array <code>['something', 'something2']</code> which I have to save to index 1 in <code>hash</code>. Then <code>hash.value?(['something'])</code> returns false. I need it to return true. How can I do that?</p>
