  # When should_receive(:sym) is sent to any object, the Proxy sends
  # respond_to?(:sym) 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 :sym, 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.
