如何在F#interactive中查看运算符的类型？

Question

我正在尝试探索运营商的类型,例如::F#interactive.

但我收到这些消息:

Unexpected symbol '::' in expression. Expected ')' or other token.

即使我用它包围它(::).

Answer 1

我是这样做的:

> let inline showmecons a b = a :: b;;

val inline showmecons : 'a -> 'a list -> 'a list

要么

> let inline showmepow a b = a ** b;;

val inline showmepow :
   ^a ->  ^b ->  ^a when  ^a : (static member Pow :  ^a *  ^b ->  ^a)
