Subject: Passing functions to function by reference
From: brianm@dealnews.com (Brian Moon)

In PHP4, you could do:

function test()
{
        return array(1,2,3);
}

$var = array_shift(test());

PHP 5.0 broke this.  There was a fatal error on the array_shift that 
only variables could be passed by reference.  There was a good argument 
for it.  So, we started migrating our code.

Well, seems this works in 5.1.  So, my question is, was it an 
intentional "fix" or will this break again and we need to continue to 
watch for this?

Brian.
