Re: Destructuring lambdas in T?
You could define your own special form, D-LAMBDA, which is
a "destructuring" lambda, in terms of DESTRUCTURE and LAMBDA.
(define-syntax (D-LAMBDA args . body)
(let ((real-args (map (lambda (x) (generate-symbol 'FOO)) args)))
(destructure ,(map list args real-args)
This has the advantage that it checks for the correct number of
arguments, but it still doesn't pretty-print the original source.
You also have to say
(define foo (d-lambda ((a b) c) (list a b c)))
(define (foo ((a b) c))
(list a b c))
I agree with Jim Meehan that it is undesirable to add destructuring
semantics to T's LAMBDA special form.
