Hi,
I'd like to make use of Java classes implementing the Java2D
PathIterator interface:

That's not very constructive at all.
I think clojure would work fine (or better) for enterprise applications. The
one thing that could pull it down is maintainability, as the maintainers
must know clojure.
There was recently a thread about working on large programs in clojure. It

Maybe this would do:
