Subject: accessing binding in eval with $SAFE=4

hi all,
can anyone explain why this doesn't work?

class MyBinding
  def my_test
    "success!"
  end
end

b = MyBinding.new.instance_eval{binding}

thread = Thread.start do
  $SAFE = 4
  cmd = 'my_test'
  result = eval(cmd, b)
end
p thread.value

i know i can't modify the binding object in $SAFE=4, but i thought i
could  access it at least. what is an alternate approach?  i am trying
to execute code in a safe(ish) way within a context of my choice.
thanks,
nick
