Rx的F＃工作流构建器(F# workflow builder for Rx)

 这里有一个很好的F＃工作流构建器：

 我一直在尝试为工作流程制作一个“使用”实现，但一直在撞墙。 也许现在为时已晚。 
 
 怎么会创造这个？ 
 
type RxBuilder () =

    // ...

    member this.Using (disposable, f) =
        Observable.Using(???)
 
 提前致谢。 

There's a nice F# workflow builder for Rx here:

I've been trying to make a Using implementation for the workflow but keep banging my head against the wall. Maybe it's too late here.
 
How would one create this?
 
type RxBuilder () =

    // ...

    member this.Using (disposable, f) =
        Observable.Using(???)
 
Thanks in advance.
