Big Freaking Numbers IV

A couple of weeks ago, I blogged about a simple way to evaluate expressions using project BigNumbers. With all of the boilerplate code still required to get anything at all, I've been wondering how to get rid of it using dependency injection or annotation mechanisms. I haven't really coded anything at all yet, but I think it would be cool to have eventually something like this:

...
@Expression("a * (b + c)") private Expression expression;
...

... and then depend on DI mechanisms to inject an Expression implementation.
