Is that really all they have in that function? It seems rather useless
to me. Why call a function just to instantiate a class like that?

Regardless, here it is trying to create a reference to a temp var.
Basically PHP will ignore the reference here, and it should work, but
you are getting a notice because the reference is being discarded.
Either drop the reference from the function definition or do:

$class =& new $classname();
return $class;

And for PHP5 you can just drop all references related to objects and it
will do the right thing.
