What's wrong with generic algoriths? An "enumeration" (an unfortunate
term, given that is it already has a very specific meaning in Ada)
smells a lot like an "iterator," so I hvae to ask why you don't simply
go that way:
generic
type Iterator_Type is private;
with function Succ (Iterator : Iterator_Type)
return Iterator_Type is <>;
with procedure Process (Iterator : Iterator_Type) is <>;
...
procedure Generic_Algorithms (First, Back : Iterator_Type);
But perhaps you're trying to do something else? It wasn't clear from
your example. As far I can tell the language already does everything
you need, so no language change is required.
