Is a higher order question:
a) a question that can take as a parameter another question

lambda-questions: anonymous questions that stand for themselves...

Anonymous functions are very important but you don't need lambda to
make anonymous functions, take look at joy

It works with combinators and it's power of function manipulation is
extreme.
Or j http://www.jsoftware.com/ though it looks like vomit has great
function facilities.
Beside you can gracefully get rid of most of the loops just by
function manipulation.
