Simple tests I've carried out seem to show that I'm able to generate a
simple function that will accept either one or two lists as arguments by
coding it in the form
func[list1, list2_:defaultList} := Module[{ }, <<stuff>> ]
and then calculating the defaultList _inside_ the module.
Seems to work OK -- but am I setting myself up for any hidden gotcha's
by doing this?
