In the extensible exceptions paper[1], which I believe is the guide behind the current Control.Exception in GHC 6.10, a SomeIOException type is discussed so that it would be possible to use the nice interface for IOExceptions. Is this implemented anywhere? In the GHC libraries, all I see is the old interface just plugged into a simple wrapper, so you have to use guard . isDoesNotExistError (for example) with catchJust to catch a certain type of exception. If not, are there any plans to implement it?
