Subject: funky alias problem


hi,

if i write

module M
  def foo
    old_foo
  end
end

class X
  def foo
    puts X
  end
  def extend_yourself
    alias old_foo foo
    extend M
  end
end

class Y < X
  def foo
    puts Y
  end
end

x = X.new
y = Y.new
x.foo    -> X
y.foo    -> Y
x.extend_yourself
y.extend_yourself
x.foo    -> X
y.foo    -> X !!!

the behaviour i want though is

y.foo    -> Y

what is the best way?

thanks many
