Subject: arg, metaclass bug found?

Hello!

A lot explore the deeps of the metaclass/idioclass stuff, so do I. I've done 
some simple tests and found what looks like a bug for me, or at last, I did not 
expected that result at all. I may be wrong, but I can't see where.

class Object
  def meta #meta is shorter than anything else
   class << self; self; end
  end
end

class Test1
  class << self
   def test
    "from Test1.meta"
   end
  end
end

class Test2 < Test1
end

Test2 < Test1 # => true

# the bug is here
Test2.meta < Test1.meta # => nil
# it should have benn true instead of nil

# this test prove that Test2 has inherited the singleton method of Test1
Test2.test == "from Test1.meta" # => true
