微软F#文档中的示例不能编译

Question

MS文档：Use interfaces to group related operations

type Serializer =
    abstract Serialize<'T>: preserveRefEq: bool -> value: 'T -> string
    abstract Deserialize<'T>: preserveRefEq: bool -> pickle: string -> 'T

如果我将其复制并粘贴到fsx脚本或dotnet-interactive notebook中，我会得到一个编译器错误，内容如下：

This construct is deprecated: ':' is not permitted as a character in operator names and is reserved for future useF# Compiler(35)

为了修复这个示例，我需要做哪些更改？

Answer 1

我认为只要在冒号之前添加一个空格就可以解决这个问题：

type Serializer =
    abstract Serialize<'T> : preserveRefEq: bool -> value: 'T -> string
    abstract Deserialize<'T> : preserveRefEq: bool -> pickle: string -> 'T

这可能是一个编译器错误。
