To keep the namespace separate I take it? In general one can hardly
tell them apart. I know I was very suprised when I discoverd that
Object starts out completely devoid of any methods. And I suspect now,
that toplevel's effect on Object is the reason why.

So by what you say I would be inclined to wonder why isn't toplevel
Object itself rather than a special instance of Object. But the reaon
it cannot be Object is because Object can not 'extend self' like
toplevel must.

So if not Kernel and also not Object, what of the merits of separate
module Main, included in Object.

  SomeClass.ancestors => [ Object, Main, Kernel ]

So that what I am trying to undersatnd. Why would you go to the trouble
to make the toplevel a (partial) proxy of Object when a self extended
module would prioved complete and seemless functionality?
