    Hmm, not sure where the misunderstanding is here.  I think it's pretty
clear: with obj1.foo, I look in the namespace associated with 'obj1'. 
With obj2.foo, I look in the namespace associated with 'obj2'.  With
(foo obj1), I look in the same namespace that functions are looked up
in.  With (foo obj2), I also look in the same namespace functions are
looked up in.  In the latter two cases, it's the same namespace.  In
the former two cases, they are different namespaces.

    It's not a grid, but a graph; cadr is not the same thing as cdar.
