Return::Value - Polymorphic Return Values

Polymorphic return values are really useful. Often, we just want to know if something worked or not. Other times, we’d like to know what the error text was. Still others, we may want to know what the error code was, and what the error properties were. We don’t want to handle objects or data structures for every single return value, but we do want to check error conditions in our code because that’s what good programmers do.
