Arie,

Thanks for calling that out. The most useful part for my case is the MonadCatchIO implementation of catch:

catch :: Exception e => m a -> (e -> m a) -> m a

Hoogle shows a few similar functions for that type signature, but they won't work for the case of catching an IOException in an arbitrary monad. Do you happen to know of another approach for catching IOExceptions and throwing them in ErrorT?

Thanks,
Eric

MonadCatchIO-transformers is being deprecated, as recently GHC has removed the
'block' and 'unblock' functions, rendering the api provided by
Control.Monad.CatchIO obsolete.
