title: Set data structure in VBA
body: <p>I'm looking for a <a href="https://en.wikipedia.org/wiki/Set_(abstract_data_type)" rel="noreferrer">set</a> data structure to use in Excel VBA. What I found so far is Scripting.Dictionary which seems to be a <a href="https://en.wikipedia.org/wiki/Associative_array" rel="noreferrer">map</a>.</p>
  
  <p>Is there also something like a set in VBA?</p>
  
  <p>Basically I'm looking for a data structure that is efficient for finding out if a particular value has already been added.</p>
