I agree -- as one of those "who disagree". The stack may be also a
good example for a use of "use" which is acceptable for me. If we define
an abstract data _type_ instead of the given abstract data object we get
calls like "Push (Stackname, Object_To_Be_Pushed)" and thats ok for me
(as long as it has the "usual" (:-)) semantics of a stack).

Fully agreed. But running into the problems with this example is much
more impressing than everything we could say.
