Though Dmitry A. Kazakov and I both like Ada, we do not necessarily
agree as to what constitutes good support of units. Ada provides the
mapping
Type * Type -> Type
and ML provides the mapping
Type x Type -> (Type x Type)
and both of these can be worthy without being universally
desirable. It might be nice to have a language which supports both of
these kinds of mappings.
