Subject: bug#14164: 'letrec' allows to refer to the values of previously bound variables
Date: Tue, 09 Apr 2013 08:41:04 +0400	[thread overview]
Message-ID: <877gkcuxi7.fsf@karetnikov.org> (raw)

According to the manual [1], this snippet:

(letrec ((a 42)
         (b (+ a 10)))
  (* a b))

should return "Error: unbound variable: a."  But it returns 2184 in
Guile 2.0.7.  Either there is a bug in the manual or 'letrec' doesn't
work properly.
