As it turns out, I was able to stop the method from binding to a

So that instead, it passed the UnboundMethod directly to
define_method.   This does what I want and seems reasonable.  Please
let me know if there are problems, otherwise, I'm a happy camper now.

    def reveal(name)
      unbound_method = find_hidden_method(name)
      fail "Don't know how to reveal method '#{name}'" unless unbound_method
      define_method(name, unbound_method)
    end
