title: Bash: command grouping with curly braces inside subshell
body: <p>When I'm trying something like this:</p>
  
  <pre><code>( echo &amp;&amp; { echo ; echo } )
  </code></pre>
  
  <p>I'm getting:</p>
  
  <pre><code>-bash: syntax error near unexpected token `)'
  </code></pre>
  
  <p>I'm sure that I need to use subshell. And I'm sure that I need grouping inside of it. So how do I avoid the syntax error?
  Thank you in advance!</p>
