Hi,
I'm not sure if I have already complatined about it, but as I have hit
that problem again, here it goes:
GNAT says that discriminants of tagged types cannot have default
values.
So this is OK:
type T (A : Integer := 0) is null record;
but this is an error:
type T (A : Integer := 0) is tagged null record;
I find it disturbing and artificial, but perhaps I don't see the big
picture. What is the rationale for this limitation?
