I had a great discussion about this very topic on
My canonical example of a macro that isn't a simple
replacement of lambda is the match macro. I use it
everyday in my programming. It's more-or-less ML
style pattern matching:
(define (map fn list)
[(head . rest) (cons (fn head) (map fn rest))]
I have mixed feelings about changing if to take
lambdas. In a sense having if as a special form falls
out naturally from 1) using the lambda calculus as a
base and 2) taking the decision to use eager
evaluation. Requiring the programmer to patch things
to be lazy in some cases feels clumsy to me.
