In the build I have here (1.0pre-3) the Puma::Token class does not have
a unit() function, nor does Puma::CUnit have a next() function. 
Puma::CObjectInfo has a NextObject(), and both Puma::List and
Puma::CScanBuffer have next() functions... I'm not quite sure how to
proceed here.  Other than that it looks to make sense to me :)

(One of my confusions has indeed been what the correct method is to
iterate through things!)
