But I kind of like the concept of "extending" the record as illustrated her=
e:

type rec1_t is tagged record
   a : Integer :=3D 2;
   b : integer :=3D 2;
end record;
function c(x: rec1_t) return Integer is (x.a + x.b);
rec1 : rec1_t;

And then rec1.c =3D 4 is true.

But what is really the problem of prohibiting to include above:

function a(x: rec1_t) return Integer is (5); =20

?

This is similar to that the following is not legal:

type rec1_t is tagged record
   a : Integer :=3D 2;
   b : Integer :=3D 2;
   a : Integer :=3D 5; -- is not legal.
end record;

?
