Any idea how I can access a class constant from within a module when that
module is include'd in the class? I.o.w. how do I make this work?

lizzy:~% cat m 
module Debug
  def debug(level, msg)
    puts msg unless level > DEBUG # XXX DEBUG is wrong!
  end
end

class C1
  include Debug
  DEBUG = 1
  def foo
    debug(1, "this is foo")
  end
end

class C2
  include Debug
  DEBUG = 2
  def bar
    debug(1, "this is bar")
  end
end

C1.new.foo
C2.new.bar
lizzy:~% ruby m
m:3:in `debug': uninitialized constant Debug::DEBUG (NameError)
        from m:11:in `foo'
        from m:23
lizzy:~%
