 There might be various points where is not properly taken care of the PHP
 4 compability. One part is to take care of passing/returning  objects be
 reference to/from functions.

 Before sniffing the overall code, I create this ticket for reference and
 to provide first examples so that a decision can be made, how to deal with
 / merge patches etc. .

 == Pass by Reference ==
 function parameters that accept objects need to set as ''pass by
 reference'':
 {{{
 function foo(&$var)
 }}}

 == Return by Reference ==
 Functions that return objects need to be set as ''return by reference'' so
 that the actual object and not a copy is returned in php 4:
 {{{
 function &bar() {
   $obj = new Object();
   return $obj;
 }
 }}}
