An alternative I though of some time back was to 'enhance' the package
construct a 'class package' or perhaps a 'tagged package'. So instead
of:
package X is
type obj is tagged
record
a : integer;
b : float;
end record;
procedure method (object : in out obj);
end X;
You could have something like:
tagged package X is
a : integer;
b : float;
procedure method;
end X;
So 'a' and 'b' would be object attributes and 'method' would be an
object method. This sort of package would essentially define a single
tagged type without all of the record definition and controlling
parameters etc.
Further you could use:
tagged package Y is new X with
c : some_enumerated_type;
end Y;
etc..
