title: HOLD how to create an associative array inside a fixed length array?
body: <p>UPDATE: ON HOLD, I JUST THOUGHT OF SOMETHING TO TRY. SORRY FOR MY STUPIDITY
  <strong>brain fart</strong></p>
  
  <p>I'm stuck trying to understand how to implement an associative array (strings as keys, doubles as values), with a fixed number of columns, inside a single dimension array (integers as keys).</p>
  
  <pre><code>//outer array:
  temperature_stations[0] = [ 
    //inner array
     ["high",25.12], ["low",21.1], ["mean",22.50], ["mode", 23.95], ["duration at mode", 120.45] 
  ];
  </code></pre>
  
  <p>from what I've read, recommendations are to use a dictionary if you want associative arrays, but it's a fixed number of "columns" for the inside array (i won't need to expand the collection), and i don't need fancy insert abilities, so this seems like the wrong object...</p>
  
  <p><strong>set and get requirements</strong></p>
  
  <p>i need to set values for each element
  temperature_stations[2]["high"] = 27.59;</p>
  
  <p>but getting results is just by walking through each element using a simple loop</p>
