Is this the stuff you're referring to which seems to be "way beyond a
simple example"? The FFI tutorial on the old wiki seems to be quite
simple. If you find the pages on the old wiki useful, then please move
them over to the new wiki. Or feel free to write some new pages that
fill the gaps you find.

There's quite a bit of Haskell code about which does FFI. From memory:
darcs, and the various database libs (HSQL, HDBC, Takusen).
