Now there is an interesting idea. Check out the attached screen shot, the
only place where CObject is actually extended is in the TclList class.
I guess this was done so that a Tcl List would not need to get converted
to a Java Vector if it was to be used from Java code. Are TclList internal
reps the only area where we have a problem? I think that is the case but
I am not sure.
