Subject: Abstract type derivation?

Message-ID: <4kb0hb$k87@dfw.dfw.net> (raw)
I want to create an abstract type that is derived from Controlled
(which is itself abstract). Either the syntax isn't clear or it can't
be done :-)
type Queue is new Controlled with private;
-- allows users to declare a type Queue
type Queue is abstract tagged private;
-- what I want, but now I don't have "Adjust" available, major
bummer.
Am I missing something obvious?
