I will trust you for the assertion about C++, as I forget too much since=
  =

that time, but your words invite me to notice the orthogonality you  =

mention, is in the big part, more in Ada than C++. Think of separation o=
f  =

hiding and attaching methods to a tagged type. That may be true for a th=
at  =

particular point, but not for the whole (just wanted to remind a detail =
 =

cannot shadow the whole). Will investigate that point later any way, as =
 =

I've never felt any lack of orthogonality with Ada here; I will try to  =

better understand what you meant.
