  # respond_to?(message) to that object to see if the method should be proxied.
  #
  # If respond_to? itself is proxied, then when the Proxy sends respond_to?
  # to the object, the proxy is invoked and responds yes (if so set in the spec).
  # When the object does NOT actually respond to `message`, an exception is thrown
  # when trying to proxy it.
  #
  # The fix was to keep track of whether `respond_to?` had been proxied and, if
  # so, call the munged copy of `respond_to?` on the object.
