No more so than C, surely. We're used to stateful APIs. They're a pain.

That's more of an issue. But the prior work has been done.
Do you have any references to this work?
I'm quite interested in this, both from a Haskell perpective (although I'm still a beginner) and from being the author of a Perl <-> Java interoperability module (see
http://search.cpan.org/~patl/Inline-Java-0.52/).
Thanks,
