Apologies, but I couldn't understand the example. In an exception where it's not even possible to know the stack trace easily, I don't expect to know the state of the computation. It's an exception -- it is alright if it doesn't have the state. But at least allow me to catch the exception in MonadIO.
Use liftIO for that; that's what MonadIO is for. I expected you were needing to go the other way, because if you have MonadIO then you have IO via liftIO. -- brandon s allbery kf8nh sine nomine associates allbery.b@gmail.com ballbery@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net
