[ need to draw uml diagrams better... ]



more points to cover...

- primitive (built-in) vs. user defined
- wrapper objects
- syntactic conventions (e.g., operator->() as operator.() and
 operator*()


then cover binding times of classes, e.g., when static methods fire,
 when
allocators, con/de/structors, dedallocators run, etc.
dynamic vs. static "typing", but types different than o-o classes

- class-less objects, prototypes instance creations, null in-situ
 creation,
Ruby oneof instances -- use classes, but act like class-less.  
 Smalltalk's
class Class.

- base class (Object)
