My, my. I'm always discovering something new about Ruby. Strange how POLS can
also mean POMS in a good way
I just discovered that a method defined at the toplevel is accessable _inside_
my objects.

聽聽c
Maybe I look foolish for not knowing this, but I really had no idea. When I
wanted this behavior before I would always put the def in module Kernel or
class Object.
How is #t getting inside r ? Does Toplevel == Object ? Guess I was thinking
that Toplevel was its own space --a subclass of Object.
I see. Thank you. Interestingly irb doesn't throw the error.

def statement at the top level defines private method in Object
class.
Why should it? If t is a private method of Object, and R is an
object, then there's no reason for it not to work.
