PHP doesn't really copy variables when you copy them, it always makes
references by default internally, and only converts them into copies
when you actually change the variable. Therefore the paradox result is
that references are actually slower than copies.

That's why it doesn't make sense to use a reference there. Also,
references can lead to quite unexpected things sometimes.
