title: scheme list equivalence comparison
body: <p>Hello I need to check if two lists have same elements in same order but I wasn't able to achieve as it seems like scheme eq? and eqv? checks by reference so giving false to such:</p>
  
  <pre><code>&gt; (eq? (list 1 2 3) (list 1 2 3))
  #f
  &gt; (eqv? (list 1 2 3) (list 1 2 3))
  #f
  </code></pre>
  
  <p>How to achieve this ?</p>
