#lang scheme/base
;; scheme/promise has srfi-45-style primitives
(require scheme/promise)
(provide (all-from-out scheme/promise))
;; TODO: there is a small difference between the primitives in srfi-45 and the
;; ones provided by scheme/promise (the latter is a bit more permissive). See
;; "library approach" in scheme/promise and see the post-finalization
;; discussion on the srfi-45 list. I (Eli) showed at some point how the
;; "language approach" primitives can be used to implement the other, and this
;; needs to be done here too.
