大家好，

我有一个场景，我有两个函数可以从相互递归中受益，但我不确定如何在F#中做到这一点

I Have a scenario where I have two functions that would benefit from being mutually recursive but I'm not really sure how to do this in F#

我的情况并不像下面的代码那么简单，但是我想得到一些类似于编译的东西:

My scenario is not as simple as the following code, but I'd like to get something similar to compile:

let rec f x =
  if x>0 then
    g (x-1)
  else
    x

let rec g x =
  if x>0 then
    f (x-1)
  else
    x

推荐答案

您还可以使用let rec ... and形式:

You can also use let rec ... and form:

let rec f x =
  if x>0 then
    g (x-1)
  else
    x

and g x =
  if x>0 then
    f (x-1)
  else
    x
