-> ,r srfi/11
-> (let-values ([(x x) 1]) 2)
; readline-input:4:17: let: duplicate identifier at: x in: (let ((x x) (x x))
; (begin 2)) [,bt for context]
-> (let-values ([(x 1) 1]) 2)
; readline-input:5:17: let: bad syntax (not an identifier) at: 1 in: (let ((x
; x) (1 x)) (begin 2)) [,bt for context]
-> (let-values ([(x 1) 2 3]) 2)

; (let-values/bind (((x 1) 2 3)) () (begin 2)) [,bt for context]
