title: Scheme several actions if an if-statement proves true
body: <p>The way I understand a scheme if-statement is that the first condition is when the if-statement is true, and the second statement is when it is false. What if I want several conditions for when the statement proves true?</p>
  
  <p>An example:</p>
  
  <pre><code>(if (= a b)
      (set! ([a 2]))  // This shall happen when true
      (set! ([b 4]))  // This shall happen when true
  
      (set! ([a b])) // This shall happen when NOT true
  </code></pre>
  
  <p>Is it possible to do something like that?</p>
