   An "Object Oriented system without any information hiding" !?
   That seems quite strange (coming from other object systems) !
   (Except if you think of CLOS as an assembly language to make higher-level
   languages)
   Getting a good style takes a lot of years with a "good"
   language. It takes even more with "bad" languages. Remember the difference
   between programs written in Basic and programs written in PASCAL.
   What about teaching lisp with "goto" instructions instead of structured loops?

Perhaps it seems strange coming from C++.  However, with a few
exceptions, Lisp-based object systems are typically considered
mechanisms for building abstractions.  Information hiding is provided
by orthogonal facilities which work for the non-object-oriented parts
of the language.  In CommonLisp, this is done with packages.  In
EuLisp and Le-Lisp, this is done with modules.  So I don't think this
depends on a view of Lisp as an assembly language, and even if you
take this view, which has some merit, the analogy needn't be extended
to using GOTOs instead of structured programming features.
