I often find the following type of incremental definition useful:

(define (foo) (display "bar"))
(foo)
;prints bar
(define foo (let ((bar foo))
              (lambda ()
                (display "foo")
                (bar))))

(foo)
;prints foobar

How do I preform this type of incremental definition with macros? I could not get let-syntax to provide the same functionality.

Currently I use plt scheme, but would like to see answers in different lisp implementations as well.

I had a pretty simple requirement in my Scheme program to execute more than one statement, in the true condition of a 'if'. . So I write my code, something like this: (if (= 1 1) ((expression1) (expression2)) ; these 2 expressions are to be executed when the condition is true (expression3)… >>> More

Does R6RS or Chez Scheme v7.9.4 have a library function to check if a list contains duplicate elements? Alternatively, do either have any built in functionality for sets (which dis-allow duplicate elements)? So far, I've only been able to find an example here. The problem with that is that it doesn't… >>> More
