Question

Is there a shorthand in scheme for ((lambda () ))

For example, instead of

((lambda ()
    (define x 1)
    (display x)))

I would love to be able to do something like

(empty-lambda
    (define x 1)
    (display x))

Answer 1

The usual idiom for that is

(let ()
  (define x 1)
  (display x))

which you can of course turn into a quick macro:

(define-syntax-rule (block E ...) (let () E ...))
