Subject: Re: local_method_missing possible

1) Wouldn't that cause infinite recursion if you called B.new.a?
2) Is this something like CLOS (common lisp object system) around
methods?  (See http://www.aiai.ed.ac.uk/~jeff/clos-guide.html).  If so,
I have an partial implementation that works in 1.8.0 (and I hope will
work in 1.8.2 final)
