Well the Object object, happening to be a module too (read class if
you prefer), is the parent of all ( almost all in Ruby 1.9) instances
in a Ruby program. For me it seems quite a good choice to
use an instance of Obejct to represent the top most "self" in a Ruby program.
It might be an instance of a special class like Toplevel (being a
singleton presumably), I would prefer that, but the actual approach is
a pragmatic one that is quite ok.

Now talking about your idea of main == Object I fail to see what that
should be good for. It is surely not the role of the (almost in Ruby
1.9) most general class in Ruby to carry the responsabilities of main.
