Description:
------------
I have really big problems with your newest change to php. having Call-time pass-by-reference has been deprecated without having objects passed-by-reference makes the usability of your language really impractical. 

example: 

function foo($var); // is by-value if you pass an object it will be copied.

function foo(&$var); // is by-reference but you cannot pass null or a value.

foo(17); // error
foo(null); // error

function foo(&$var = null); // error

Because you have unsuitable method signiture overloading and now no call-time pass-by-reference an efficient way of designing applications or libraries in your language is now impossible.

It's a pity. At the moment I don't feel like to finish my php projects.

Marcus

You of course cannot pass a constant as a reference.
So you also cannot pass NULL by eference.
But you can pass a pareameter set to NULL of course:
  function t(&$p) {}
  $x = NULL;
  t($x);

Having said the above it should be clear why you can't initialize function parameters which are passed by reference. The initialization value would be a const.

Seems you should redesign your apps/libs to something that makes more sense.
