title: unpack string in variable
body: <p>In Bash, I can use the following code:</p>
  
  <pre><code>[ "$sshcmd" = "" ] &amp;&amp; sshcmd="ssh -someopts myhost"
  
  $sshcmd "echo hello world"
  </code></pre>
  
  <p>In ZSH, the same code does not work because it tries to find a "ssh -someopts myhost" executable. How can I do the same thing in ZSH?</p>
  
  <p>Thanks, Albert</p>
