Aha!  I didn't notice that Object>>allSubclasses returns both classes 
AND metaclasses.  It does this in VisualWorks and Squeak.  
VisualSmalltalk on the other hand, does behave as I thought (returns 
like kind, either class or metaclass).  Of course I realize that 
MetaClasses are subclassed from Object.  Personally I prefer the 
VisualSmalltalk behavior because it lets me easily get classes and 
metaclasses independently, or both.

I wonder if the ANSI standard defines behavior for this.

Thanks John.  :-)
