I don't think it contradicts my example; I'm evaluating "puts a"
inside a method where a has not been defined.  Morton's examples
either use the top-level binding explicitly, or set an a variable in
the method.  My example doesn't do either, so the top-level assignment
to a is essentially playing no role.
