Yeah, I was putting off learning how to deal with conditional compilation, but now that I’ve looked it seems easy enough. Your definitions look right to me. > Finally, would you also like to add wrapped functions for alloca and > friends from all the Foreign modules? Michael Snoyman asked me the same question [1], and my thinking is that using liftIOOp with the Foreign allocation functions is already just as easy as using liftIO with normal IO actions: liftIOOp alloca $ \ptr -> frobnicate ptr liftIOOp (allocaBytes 17) $ \ptr -> frobnicate ptr which suggests that maintaining a wrapper library would not be much of a win. The same goes with functions like withMVar. I’d be happy to hear arguments otherwise; or maybe the right answer is to clarify this in the documentation somehow?
