title: can we use foreach loop like this in tcl?
body: <p>I have two list:</p>
  
  <pre><code>set lista {5 6}
  set listb {8 9}
  </code></pre>
  
  <p>and the following code is used to loop the two lists:</p>
  
  <pre><code>foreach listaelement listbelement $lista $listb {
      puts $listaelement &amp;listbelement 
  }
  </code></pre>
  
  <p>how can we use foreach to achieve the output is:<br>
  first element from lista, first element from listb,<br>
  first element from lista, second element from listb,<br>
  second element from lista, first element from listb,<br>
  second element from lista, second element from listb,</p>
  
  <pre>
  5 8
  5 9
  6 8
  6 9
  </pre>
