OCaml的语法是否像Haskell的++？

Question

我知道OCaml有List.append，但它有像Haskell的++那样的运算符吗？

Answer 1

For lists: 对于列表：

# (@);;
- : 'a list -> 'a list -> 'a list = <fun>
# [1;2;3] @ [4;5;6];;
- : int list = [1; 2; 3; 4; 5; 6]

For strings: 对于字符串：

# (^);;
- : string -> string -> string = <fun>
# "abc" ^ "def";;
- : string = "abcdef"

Answer 2

Also, you could just say yourself 另外，你可以说自己

let (@) = List.append

or 要么

let (++) = List.append

if noone had yet done it for you in the standard library. 如果还没有人在标准库中为你做过这件事。
