I didn't want to disturb you so much I did. After all I solved that problem
by adding instanceVariable to class MetaClass (it is easy) and created
some protocol between Class and MetaClass. Now it's functional.
Please excuse my mistake.
Thanx

Peter.

Some time ago I sent out a proposal for implementing namespaces that
basically added a namespace variable to every object in the system, and
altered the behavior of the VM so that it would execute a method only in the
namespace (or the super-namespace hierarchy) of the object that called it.
While this does not implement everything in the Namespace proposal (such as
resolving references to system and class-wide objects like class variables
and pool dictionaries), it is the most radical
>surgical procedure of the project and can not be accomplished without
altering the VM.

about what you are trying to do, not just how you trying to do it.  For
instance, if you simply want to add some attribute to any object (but not
necessarily every one in the system), you might want to consider a mechanism
similar to the dependents dictionary that makes every object *appear to*
have an instance variable named dependents.
