body: <p>Does this code</p>
  
  <pre><code>if (typeof importScripts === 'function') {
  
  importScripts('somelib.js');
  
  }
  
  //some code between
  
  if (typeof importScripts === 'function') {
      var i = some_function_from_imported_lib(params);
  //CODE CODE CODE
  }
  </code></pre>
  
  <p>is the same as </p>
  
  <pre><code>if (typeof importScripts === 'function') {
  
  importScripts('somelib.js');
      var i = some_function_from_imported_lib(params);
  //CODE CODE CODE
  }
  </code></pre>
  
  <p>?</p>
  
  <p>In other words, does it matter <code>importScripts()</code> is wrapped by some parenthesises or not? Does it matter for scope of functions and variables inside <code>somelib.js</code>?</p>
