well we don't need to go that far.  We now have overloading on arity - we can just define a series of methods 
for list, list(_), list(_,_)  --- or if you prefer, retain the interface from the previous version. 

the real advantage of doing it that way is that without either indexing or "lineups",
we can use [ ] for generics without any ambiguities
