And something that should be said again: Adding the possibility of using traits to squeak will *not* slow down any existing code at all.
Thanks marcus. I think that I lost a part of my faith and energy in the process of talking about traits...
Traits are the most backward compatible, non-intrusive extension of Smalltalk to provide reuse orthogonal to inheritance we could imagine. The model of traits is the simplest one we could think of and (not as researcher since nathanael worked on extended versions that we will never push in Squeak since there are less backward compatible and more conceptually aggressive :).
