Subject: Re: "Self" confusion

See comments in the code.

class Yoghurt
  def self.a # Here self is the Yoghurt class. This defines a method
on the Yoghurt class
    "yoghurt self"
  end
  def Yoghurt.a # This does exactly the same as self.a, just another
way of doing it.
  # This overwrites the previous version, which is quite legit in Ruby
    "yoghurt"
  end

  p Yoghurt.a
  p self.a
end


def self.a
  # This defines a on self, which is an instance of Object.
 "object self"
end
def Object.a
  # This defines a on the Object class
 "object"
end
p Object.a
p self.

And the output I'd expect is:
> "yoghurt"
> "yoghurt"
> "object"
> "object self"
>
>
