Hi,
this is not a chicken-specific question.
Does anyone know of any existence of a lazy-let macro,
which does the following?
<convert from>
(lazy-let ([a (get-a)][b (get-b)])
(if (condition) a b))
<into>
(if (condition) (get-a) (get-b))
the above example is fairly easy, but how about this;
<from>
(lazy-let ([a (get-a)][b (get-b)])
(if (condition)
(begin (display a) a)
(begin (display b) b)))
<into>
(if (condition)
(let ([a (get-a)]) (begin (display a) a))
(let ([b (get-b)]) (begin (display b) b)))
My question is whether this is a known situation and there exists
a macro for it, if no, is it feasible, or could this be
written in a macro in general way?
I hope my explanation does make sense.
Daishi
