Matthew, the entire Haskell.org website is a Wiki. You might spare someone else the pain that you went through by starting a "Duffers guide to the Haskell FFI" that contains the information you wished you'd known on day 1. I'm sure you'd get lots of help on the #haskell IRC if you did so.
The old wiki has several FFI related articles. I myself contributed example code with callbacks and a data structure as I couldnt find one when I was playing with FFI. Perhaps it could be augmented to include an array example. (Also if anyone wants to make the example better, that would be great, I am no haskell expert). http://www.haskell.org/hawiki/FfiExample http://www.haskell.org/hawiki/FfiTutorial http://www.haskell.org/hawiki/FfiCookbook Also, perhaps this should be reachable somehow from the new wiki?
