2009/6/2 lowly coder lowlycoder@huoyanjinjing.com:
are there any amcros that play well with destructuring bind of define-type's ? I just want to check to see if there's a pre-existing solution before re-inventing my own.
I find myself writing way too much code of the form:
(define-type foo a b) (define-type bar c d)
(lambda (x) (let ((c (bar-c x) (d (bar-d x))) (let ((a (foo-a a) (b (foo-b b)) ...
This is the kind of thing where macros get over-used
(define (with-foo f body) (body (foo-a f) (foo-b f)))
