The following behavior of `let' seems to be wrong.

guile;; inconsistency between let and lambda
(let ((go #f)

((lambda (a b)
(set! alist (cons (cons a b) alist))
(set! a 100)

((1 . 2) (100 . 2) (1 . 2) (100 . 2))

For what it's worth, my current Guile, from Git post 1.9.14, gives ((1
. 2) (100 . 2) (1 . 2) (100 . 2)) for both cases.
