Thank you to everybody. I think I will see how far I can get with 
func_get_arg - it may solve the problem.

The other hackish solution I thought of is to put the object arguments 
into a key/value array and pass the array as a single argument to the 
function. That way I can check for the key and if the key is set, grab 
the object associated with it.
