Can I urge any of you who learn stuff that "I wish I'd know at the beginning" to add that information to GHC's FFI Wiki page? http://haskell.org/haskellwiki/GHC/Using_the_FFI Anyone can add to this material, and it's extremely helpful to jot down what you've learned while it's fresh in your mind. The current page is largely about C++ bindings, but that's only because that's what the last contributor was interested in. Feel free to re-structure it, add new sections etc. Simon | -----Original Message----- | From: haskell-cafe-bounces@haskell.org [mailto:haskell-cafe-bounces@haskell.org] On Behalf Of Brian | Hulley | Sent: 27 June 2006 22:56 | To: Jared Updike | Cc: Haskell-cafe | Subject: Re: [Haskell-cafe] Are FunPtr's stable?
