title: Best way to find if a string is in a list (without generics)
body: <p>I want do something like this:</p>
  
  <pre><code>Result = 'MyString' in [string1, string2, string3, string4];
  </code></pre>
  
  <p>This can't be used with strings and I don't want to do something like this:</p>
  
  <pre><code>Result = (('MyString' = string1) or ('MyString' = string2));
  </code></pre>
  
  <p>Also I think that creating a StringList to do just this is too complex.</p>
  
  <p>Is there some other way to achieve this?</p>
  
  <p>Thanks.</p>
