Hello!

Guile-Lib’s md5.scm does something like:

--8<---------------cut here---------------start------------->8---
(define f-ash ash)

(define (ash x n)
  (modulo (f-ash x n) #x100000000))
--8<---------------cut here---------------end--------------->8---

At -O0 and -O1, this has the desired effect: ‘f-ash’ is an alias for
(@ (guile) ash).

However, at -O2 and above, ‘f-ash’ is eq? to the ‘ash’ defined right
below it.

This seems to contradict R5RS (info "(r5rs) Top level definitions").

Thoughts?

Ludo’.
