       Version 3.0.0:

            - Namespace changed from System.Option to Functional.Option
            - Implicit Conversion from Option<T> to <T> has been removed.
        - Option now implements IEnumerable<T>
        - ToOption() extension method added for regular and Nullable types.
        - Pattern matching is now a function call in the form:
               None: () => { /* Action when the Option is None */ },
               Some: value => { /* Action when the Option is Some<T> */ });

           var result = option.Match(
               None: () => "None",
               Some: value => value.ToString());
