I know where you are coming from, this is a nice pattern, but in this
case t is a return value of Resolv::DNS::Message#question, and I have to
answer the question. How I answer the question depends on the question
(of course!), but is not part of the behaviour of the question,
different "answers" answer the question in different ways.

Thanks for all the suggestions, folks.
