Keith's already started work on his declarative validation framework!
The code is in the sandbox's org.springframework.rules package. There's
also a page about it in the wiki:

From my (very brief) look at what you've done with Valang it appears
there is a strong synergy between the 2 projects. Your functions and
predicates packages have a lot of similarities with Keith's closure and
constraint packages. I suspect that it wouldn't be hard to reimplement
your Valang parser so that it generated Keith's Rules.=20
