Something else: In the soon to be released base-4.3 the block and unblock functions will be deprecated in favor of mask. It would be great if you can also add these new functions to Control.Exception.Peel:
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?
