I think it's bitrotted a bit, but http://code.google.com/p/hoc/ was a bridge
that worked at one time with haskell and obj-c. might be worth mining for
ideas, at least.

What model are you thinking of? Importing haskell code into an obj-c
project, or running everything from haskell? If it's the first, my Hubris
project may be interesting (http://github.com/mwotton/hubris) - has a bit of
code for automatically testing whether haskell expressions are exportable to
ruby.
