Which means that his design is actually much more powerful then that
of Smalltalk... we do have meta classes, but they are not really
usefull. e.g., we can't
enable persistence through changing the metaclass of a class. A
better meta-layer in Squeak would be really nice to have... but quite
hard to do really right.
