Subject: Where does this "global code" fit in?

You'll excuse me, but I'm coming from a Visual Basic background and am
trying to give myself a good OO knowledge using Ruby (I just LOVE the
Ruby language, having failed miserably at Smalltalk!).

So this is a relatively simple OO question.

Supposing I have a simple ruby program containing just this code:


class Window
  #some code here (assume a method "show" is defined somewhere)
end

w = Window.new    #<<<
w.show            #<<<


Now I understand that Ruby is pure-OOP.  And I guess that class
"Window" is implicitly deriving from superclass Object.

It's the two lines at the end that confuse me.  My natural though is
they are "global", but in a pure-OO world, they've got to fit into a
class somewhere?  If so, are they actually fitting into (extending)
class "Object" in some way?  Where?  How?

Ta muchly

Glenn.
