Trailing undefineds are treated as "not passed" in the overload 
resolution algorithm (step 4).  There is still a note just below the 
overload resolution algorithm mentioning the fact that ES6 might have 
been going to change to treat all explicit undefined values as missing. 
  Has the ES6 change been made?
