IResult - A Robust Option Type for C#

In this article, I discuss IResult, which I created based on the concept of an Option (or Maybe) type from functional programming languages. IResult utilizes some of these new features of C# 7.0 to emulate an the Option type from F#, including helper functions like Bind, Map and Fold. I look at reading input, parsing input, IResult extension methods, and how to put it all together.
