title: Parentheses for subshell don't work when stored in a variable
body: <p>The command:</p>
  
  <pre><code>( echo 1 )
  </code></pre>
  
  <p>works fine when I input it in the command line but if I store it as a variable and call it, it gives the error:</p>
  
  <pre><code>(echo: command not found
  </code></pre>
  
  <p>Code:</p>
  
  <pre><code>input="( echo 1 )"
  $input
  </code></pre>
  
  <p>Why doesn't it evaluate the parentheses the same way and put it into a subshell when I call it this way?</p>
