I dont know if the following will clarify or muddle but still here it
goes :
In your original case, the procedure P was defined only for FOO for
which there is no A defined.
On the other hand in Dmitry's modification P is defined for the whole
family rooted in FOO ie FOO'Class. So A becomes dispatching.
I think there is nothing wrong with the declaration of A and nothing
for the compiler to complain about.
HTH. regards, srini
