Subject: Method call within a class

Hi all,

Maybe I miss something. But I am confused about method call within a
class. What is the format for that? I just copy some code segments from
the forum as follows:

module Enumerable
 def each_with_index
   i = 0
    each do |elem|
       yield elem, i
      i += 1
    end
  end
 end

class Array
   def each_with_index
    size.times do |i|
      yield self[i], i
     end
   end
end

So
1) which one is the reciever for "each"?
2) which one is the reciever for "size"?

Do they default to self?

Thanks,

Li
