Thanks to everyone, I decided to modify the existing original method and
use func_get_args() to grab the arguments passed to it. It's not
perfect, because I lose out on the automatic value assignment that I
would have with a regular method (i.e. function foo($bar, $fubar=0) etc)
but it will do at a pinch.
It's a shame this sort of overloading isn't supported, as it could be
quite a useful feature, but it's not a complete show-stopper.
Thanks,
Ash
