It would be nice to be able to alter existing chunks, by inserting stuff later,
|
|
for example:
|
|
|
|
@chunk[<c>
|
|
(define-syntax-rule (double x)
|
|
(+ x x))]
|
|
|
|
But we would actually want:
|
|
|
|
@chunk[<redef-c>
|
|
(define-syntax-rule (double x) -- should be greyed out
|
|
(let ((x-cache x))
|
|
(+ x-cache x-cache))) -- everything except the changed bits should
|
|
-- be greyed out]
