Subject: understanding inheritance and class singleton methods

Hi,

I'll start with what I understand:
class Foo
   class << self
      def hi
         puts 'HI'
      end
   end
end

Creates an instance of a singleton class that has the method #hi. So 
Foo.hi calls the method defined in the class of Foo -> the singleton 
class (which inherits from Class)

My question:
class Bar < Foo
end

Bar.hi --> 'HI'

It looks like two things are happening: 1. Bar points to Foo, so 
instances of Bar lookup methods in Foo also. 2. The instance Bar has a 
class that inherits from Foo's instance class.

Is this correct? Is there somewhere where I can find the exact flow of 
'<' (and '<<')? (or for that matter, specifications how 'splat' behaves 
and the '&' operator before blocks)

Thank you,
Ittay
