The example is simplified, but I dislike returning null in my own code. The function will always execute, left or right doesn't matter it's mapped across in the ResultObject class.

The function must return an IResult, the ResultObject analyzes the IResult checking for IFail or IOk. If it's IOk the value of type T is retrieved from the Value property of the IOk object and returned, the Some property defaults to true. If the IResult is an IFail, Some is set to false, it copies the message from the IFail object into the ResultObject, and returns the value the was supplied to its constructor.

I'm just sharing something I find useful, and I hope I can make it useful for others as well. Thanks for the questions.
