Exercise 4.73: Why does flatten-stream
|
||
|
|
use delay explicitly? What would be wrong with defining it as follows:
|
||
|
|
|
||
|
|
|
||
|
|
(define (flatten-stream stream)
|
||
|
|
(if (stream-null? stream)
|
||
|
|
the-empty-stream
|
||
|
|
(interleave (stream-car stream)
|
||
|
|
(flatten-stream
|
||
|
|
(stream-cdr stream)))))
