New Comment:
Along workarounds I mentioned also one solution. I'll document that.
foo(NULL) is maybe the most elegant solution in your eyes however this
manner is deprecated :-(.
I'm not sure why it's deprecated (probably for performance reasons) so
I can't explain why it's deprecated.

Workarounds? How elegant! :P
You got to be kidding, right? We were talking improvements!
The workarounds are known by know. Is there nothing more elegant like
foo(NULL);
------------------------------------------------------------------------

Possible solution:
function foo (& $var){
if (is_null($var)){return 0};
return(1);
}
$somevar = null;
foo($somevar);
Possible workarounds:
allow_call_time_pass_reference can be set on per directory basis.
@ can be added before function call (with side-effect of not displaying
any errors of course)
There's no other solution AFAIK.

I was wondering about this too... how can you deprecate this and not
tell the community what is going on? I found only very little info
about this issue out there. But meny people seem to truggle with it.

above: sorry, typo:
function foo ($obj){
should obviously be
function myfunc ($obj){
i was copying...

I agree totally! We used to be able to do the following:
myfunc(& $someobj); #and
myfunc(''); #this, if nothing passed
function foo ($obj){
if(is_null($obj)){...};
...
}
At this point we have to pre-check everything and do some massive
recoding! What is an easy solution for this or waht were you thinking
when chaning this? How do I pass 'nothing' now?
