You need some clearl defined scope where the format parameter would be
visible:
generic
with ... Something;
type Generic_Mess is ...;
...
-- many lines below
procedure Bar (Y : Generic_Mess; X : Something);
-- even more lines after. Is this OK?
procedure Foo (X : Something) return String;
But, surely, discriminants do the job to me.
In my view any parameters must be a value and have a proper type. If you
wanted to parametrize using types make them first-class citizens. However,
there are better design methods than type parameters and blowing up the
language with generics.
