Is a higher order question:
a) a question that can take as a parameter another question
b) a question that returns a question
c) both?
2. In practice, are questions that return questions used frequently?

I believe the most important aspect of higher order questions is
lambda-questions: anonymous questions that stand for themselves...

Perhaps these are related to the famous "why?" operators I've heard so
much about.

Of course, our research here a few years back looked at implementing the
WHY-NOT operator as well[1].
