;;; This module is temporary, containing just the things we need right

(define-module (srfi srfi-1)
  #:use-module ((hoot lists) #:select (alist-cons fold))
  #:export (fold-right)
  #:re-export ((acons . alist-cons)
               fold))

(define (fold-right f seed l)
  (fold f seed (reverse l)))
