title: What kind of Ruby data structure is this?
body: <p>A very simple question, but I'm new to Ruby and not able to determine the name of this type of data structure:</p>
  
  <pre><code>location = 145.6, 56.644
  </code></pre>
  
  <p>I searched for point, pair, comma-seperated value etc. but was not successful. Could you tell me what this is?</p>
  
  <p>Thank you</p>
