Description:
------------
It would be useful if you could leave out optional Parameters when calling 
Functions, but specify others that come after that certain Parameter. I suppose 
the Script will explain it a little better.

Test script:
---------------
<?php

  abc("...", , 123);
  abc("...", 2, , chr(10));

  //Like in list, where you can leave out certain Elements
  list($a, $b, , $d) = explode(",", "a,b,c,d");

  function abc($d, $e = false, $f = 123, $g = PHP_EOF) {
    return "something";
  }

?>

Expected result:
----------------
.

Actual result:
--------------
