The code below (kons) gets flagged in R5RS: define: not allowed in an expression context in: (define dispatch (λ (m) (cond ((= m 0) x) ((= m 1) y) (else (error "Argument not 0 or 1 -- KONS" m)))))
Works fine if I replace the lambda symbols with "lambda". Cause? Michael ============= >From page 91 in SICP (slightly modified): (define kons (λ (x y) (define dispatch (λ (m) (cond ((= m 0) x) ((= m 1) y) (else (error "Argument not 0 or 1 -- KONS" m))))) dispatch)) (define (kar z) (z 0)) (define (kdr z) (z 1))
