Class variables are still inherited?

Hi ruby-talk

It's said everywhere that class variables are not inherited anymore in
newer versions of ruby. I experience a different behaviour, can you give
me any hints about what I'm doing wrong?

class Foo
  @@a = 1
  def self.moo() @@a end
end

class Bar < Foo
  @@a = 2
end

Foo.moo == Bar.moo # both are 2

My ruby comes from this package: ruby-1.9.1-p0.tar.bz2

For a while there was a change so that they weren't shared in the
whole hierarchy, but it got reverted.
