title: VSCode add parentheses when autocompleting functions
body: <p>Is is possible to tweak VSCode so that when function gets autocompleted, it is written with <code>()</code> instead of just plain function name?</p>
  <p>For example when I type <code>str</code> and autocomplete to <code>strlen</code> I would like to get <code>strlen()</code>, it saves quite some time.</p>
