Description:
------------
Introducing a dummy variable assignment in function arguments where a reference is 
expected should be a reasonable workaround for the limitation that only variables 
can be passed as reference. But, it causes a StrictStandards warning.

Separating it into two statements:
$dummy=0; foo($dummy);

of course works.


Test script:
---------------
<?
function foo(&$a){	
}
foo($dummy=0);


Expected result:
----------------
No warning.

Actual result:
--------------
Strict Standards: Only variables should be passed by reference in .. on line 4
