hehe :) the power of pointers pointing the the same things and traits
to not have state so
no offset mess.
yes the only thing is that when sharing compiled method is that we have
to copy the ones
that contains a super reference. But this a smart trick from nathanael.

ClassBoxes :) (Modules with local rebinding) soon we will have a public
paper and alex is reimplementing it influenced by the implementation of
Steven Pair for multiple namespaces.
A smalltalk without direct access to instance variables. That's an non
conceptual one :)
Open privacy for traits. Quite cool but not yet done....
at the end we hope to have our own language :) possibly with scripting
facilities, reflection, mirror and modules. We will get there I hope
this is too exciting.
