title: SML/NJ: How to use HashTable?
body: <p>I really want to create a HashTable in SML, it seems there already is a structure for this in SML/NJ.</p>
  
  <p>The question is, how do I use it? I've not fully understood how to use structures in SML, and some of the very basic examples in the book I read gives me errors I don't even know how to correct, so using the HashTable structure might be an easy thing, but I wouldn't know. If someone could explain this, then that'd be wonderful too!</p>
  
  <p>I'm thinking it's something like this:</p>
  
  <pre><code>val ht : string * int HashTable.hash_table = HashTable.mkTable();
  </code></pre>
  
  <p>???</p>
