[ikarus-users] SRFI-1 in Ypsilon

[Eduardo Cavazos]

Derick,

Here's what I'm getting when I load SRFI-1 in Ypsilon:

~ $ rlwrap ypsilon
Ypsilon 0.9.6-trunk/r503 Copyright (c) 2009 Y.Fujita, LittleWing Company
Limited.
> (import (srfi :1))

error in define: attempt to modify immutable binding
  >  (define (cons* first . rest)
       (let recur ((x first) (rest rest))
         (if (pair? rest) (cons x (recur (car rest) (cdr rest))) x)))
  ..."/home/dharmatech/scheme/srfi/%3a1/lists.sls"

Note to everyone else; the R6RS SRFIs underwent an overhaul recently so
you might wanna test your code against the latest revision.
