Not quite. In smalltalk, a class is actually an instance of another class
(called a meta-class) so classes are actually first-class objects with
behaviour, etc. (Java has something like this, but not as extensive).
With this type of facility, you can "reflect on" or determine the attributes
and behaviour a class has at runtime, and even make additions and
modifications. It's very useful when building dynamic systems, 
especially ones that have an uptime constraint of 24-by-7.
Anyway, one more question: I think Greg Neagle mentioned that he
believed the first release of FB^3 didn't really support encapsulation
(all data members are public). Can you comment on this?
Thanks (as usual) for the info...
