title: Tuple Concatenation in Chapel
body: <p>Let's say I'm generating tuples and I want to concatenate them as they come. How do I do this? The following does element-wise addition:</p>
  
  <p>if <code>ts = ("foo", "cat")</code>, <code>t = ("bar", "dog")</code></p>
  
  <p><code>ts += t</code> gives <code>ts = ("foobar", "catdog")</code>,</p>
  
  <p>but what I really want is <code>ts = (("foo","cat"),("bar","dog"))</code>.</p>
  
  <p>So I guess the first question is "does Chapel support tuple concatention?", then "is there a binary operator/function for it?", then "if not, what is a good way to do it?", and lastly "make my life easier if you know a better way of living".</p>
  
  <p>Please address the questions in order.</p>
  
  <p>I appreciate the help!!</p>
