I am silly : I was just talking about interfaces (reinvented the wheel, =
I  =

only attempted to use interface for =E2=80=9Csynchronized interface=E2=80=
=9D so far, so  =

did not realized immediately).

So what about an Ada profile where we would derive from interface only ?=
  =

Tagged type as implementation of interfaces only, and disallow derivatio=
n  =

 from tagged.

Could be a good Ada profile ?

Do someone see a flaw to be reported here ?
