Subject: class inheritance and class constants

------------------------
class A
  HELLO = "Hello I'm A"

  def hello
    puts HELLO
  end
end

class B < A
  HELLO = "Hello I'm B"

  def hello2
    puts HELLO
  end
end
------------------------

B.new.hello
=> "Hello I'm A"   (ouch...)

B.new.hello2
=> "Hello I'm B"


Workaround (but ugly):

-----------------
class A
  def hello
    puts self.class::HELLO
  end
end
-----------------


So, if a contstant appears within a method, its value is evaluated for
the class in which such method is defined ("hello" is defined in class
A not in B, so it takes HELLO from class A).
I don't like this behavior (just my opinion). Do I miss something?

Regards.
