Yeah, I'm happy to attack that problem. The key is finding a useful API
that you actually can work with for real problems. This looks like a
good step -- and interesting to see how you're needs differed from

I'm happy to -- if people need a slightly different API, we should do
what we can to support that.
The goal is to make binary hacking in Haskell painless, so anything that
helps that goal, is good :)
