In PHP4, you could do:

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?
In 5.1 this now throws an E_STRICT instead of a warning. It is still a
bad idea to pass a tempvar by reference, so yes, you should strive to
write E_STRICT clean code.
