Here is another attempt at Maybe, this time with just some objects and helper functions.
"Maybe" itself becomes only an abstract idea that mentally captures either Nothing or Just. I rather like this result, but the possibility of real type checking is out the window.
This example is a bit more complete than the class example because I wasn't distracted by class boilerplate and I needed to implement the join method before I could test the internal values.
