Can someone check base_url() and base_url("param")

I make extensive use of the base_url() function in my code... and it still seems to be working fine under 4.0.4 (and some of its later commits).

Though, I typically use it like this:

Code:

if (isset($_REQUEST))
{
   unset($_REQUEST);
   return redirect()->to(base_url());
}

or

Code:

if ($honeypot->hasContent($request))
{
   return redirect()->to(base_url('Index/tools'));   // that'll feck 'em!
}
