PHP5 and pass by reference bug.

So, I'm getting all these errors/warnings in PHP5 now saying that I have to put the & on the function and not in the passing (which sorta makes sense and puts the burden on the function rather than the user, which I like too). So I spend the time to go and fix several thousand lines of code. Then I start to see these other errors... Maybe I'm missing something, but this seems like a glaring bug in passing by reference that nobody caught... say you have function foo(&$bar) { } well that works great as long as you use it like foo($x); but if you try foo("something here"); Or foo( array('a','b','c') ); it shits the bed. :-(
