Over in OCaml-land, I have taken it upon myself to address this: http://gaiustech.github.com/ociml/

Takusen already supports Oracle (and other rdbms) in a resource precise and good performance way, if that's what you're talking about implementing: http://projects.haskell.org/takusen/

Ah, interesting - I was only aware of HDBC and HSQL. Which in turn begs the question, why isn't this better known among (us) Enterprise dev types?

I'm not certain, but I think the biggest problems getting in the way of Takusen's greater adoption are: * It requires a deeper understanding of Haskell than HDBC due to use of functional dependencies, rank-2 types, and left-fold enumerators. * Less documentation than its competitors * The name is good (it's the japanese word for oracle), but doesn't evoke "that's clearly a db library" in most english speakers. As the current maintainer (and I've been a really lazy maintainer, still hoping to find a proper long term maintainer), I'm interested in any feedback about Takusen. Things I would like to eventually implement: * HDBC compatibility layer to make it easier to transition from HDBC to Takusen * Replace the left-fold enumerator code with a proper iteratee library (Takusen is by Oleg but predates his work that generalized the approach).
