We are describing ruby....Check this fragment out and run it in
Ruby:
module Foo
def bar
puts "BAR yarr"
end
end
include Foo
9.bar

top-self (instance of Object you are doing the include in) provides its
own 'include'. This include actually includes the module arg in Object.
You just added your own Kernel-like module into every class (because it
got included in Object).
I do not know where this is documented in pickaxe, but Ruby defines this as
well. Its not a bug...Its a feature. :)
