For some reason this: (for/last : (U Index #f) ([i : Index (ann (in-range 5) (Sequenceof Index))]) i) Is giving me this error: . Type Checker: type mismatch expected: False given: Index in: (for/last : (U Index #f) ((i : Index (ann (in-range 5) (Sequenceof Index)))) i)
Why is it expecting False? And is there some type annotation I can put somewhere to fix it or anything? ____________________ Racket Users list: http://lists.racket-lang.org/users
