Description:
------------
Please undreprecate Call-Time pass-by-reference, since it is a fully supported and used way of programming style in almost EVERY serious and "big" language!

Reproduce code:
---------------
If you have any kind of class or stack of functions you surely want to keep lines of code as short as possible. on the other hand you surely don't want to "copy" your variables just to call a function...

example:

building an XML document, while using a (sub)function in order to create only sligthly different paths:

private function _prepareRequest()
 {
   //[some other code]
    $this->_StoreInterval("from",&$xmlwriter,$this->startdate);
    $this->_StoreInterval("to",&$xmlwriter,$this->enddate);
   //[some other code]
 }

private function _StoreInterval($kind,&$xmlwriter,$date)
 {
    $xmlwriter->startElement($kind);
    $xmlwriter->writeElement("day",date("d",$date));
    $xmlwriter->writeElement("month",date("m",$date));
    $xmlwriter->writeElement("year",date("Y",$date));
    $xmlwriter->writeElement("hour",date("H",$date));
    $xmlwriter->endElement();
 }

Expected result:
----------------
in 5.3.0 this still works, but got an warning because this is "deprecated"...

Actual result:
--------------
actually this should be working anyway, since i don't want to waste memory just to copy and paste back results from this subfunction. 

if this won't work it makes - to some extend - building functions useles.
