I'm not sure what you mean about new *classes*. It is certainly true
that I didn't do anything prevent the user from calling "b" twice on the
same A instance, thus getting two different objects pointing at that
instance:

a = A.new
b = a.b # b is an instance whose "@a" points at "a"
bb = a.b # bb is a different instance whose "@a" points at "a"

But that's easy to solve if desired. Obviously the real problem here is
that I couldn't fathom what the OP was actually trying to *do*. m.
