title: Can I add a new value in the braces (permutation) inside a bash array?
body: <p>I would like to add a new value to a list that is inside of an array element.<br>
  Is there an easy way to do that?</p>
  
  <p>I don't think this is an associative array.  I tried to updated the element as if it were and I get an error message stating "cannot assign list to array member".</p>
  
  <pre><code>temparr=( d{a,e,i,o,u} )
  temparr[d]+=("y")
  echo "${temparr[@]}"
  </code></pre>
  
  <p>I'm hoping to see this in the output:</p>
  
  <pre><code>da de di do du dy
  </code></pre>
