It's best to avoid passing non-scalars around that way I have to say I disagree with that as stated. Certainly, there are many cases where passing a reference is preferable, but it depends on the situation. My default is to pass a simple list and switch to passing references when there's a clear need. I'd even go so far as to say it's best to err on the side of not making references when they're not needed.
