Re: optimizing lazy sequences: srfi-41 vs delayed continuation with values + promise vs delayed continuation with cons + lambda

[Amirouche Boubekki]

(define (lazyseq-with-stream)
  (list->stream (iota max)))

This is wrong.

It must be implemented as:

  (define-stream (lazyseq-with-stream)
    (stream-let loop ((v 1))
     (stream-cons v (loop (+ 1 v)))))

I get the same segfault with the following error:

  Too many heap sections: Increase MAXHINCR or MAX_HEAP_SECTS
