I am getting confused on the purpose of the meta class instance variable slot.
(The one I am looking at when I get a class in the SystemBrowser, and click the
"class" selection.)

What is the purpose of this construct? My first guess was that when I fill in a
name in the "class instance var" list, that this would show up as class
variables in the regular class (and its subclasses). In other words...



   ....                  ...
     |                    |
    Foo                  Foo class   (the meta of Foo...)
     ClassVars             InstVars
     InstVars             

  

I thought when I wrote into (Foo class) a new InstVar, that I would get
automatically a new ClassVar in Foo, and its subs. That clearly is not what I
am getting. 

Can someone enlighten me please?

Thanks,
