Functional Java

```
Hi there,

I don't know what the scope / feasibility of this would be, but it would be
really cool if you could integrate with the functional-java library
(http://functionaljava.org/). They already have classes to provide similar
functionality to your Option, Func etc. Plus, they've got a lot of other cool
utility functions that you could utilize in your library.
