| type IOError = IOException |
| The Haskell 98 type for exceptions in the IO monad.
In Haskell 98, this is an opaque type. |

| catch :: IO a -> (IOError -> IO a) -> IO a |
|
| try :: IO a -> IO (Either IOError a) |
| The construct try comp exposes IO errors which occur within a
computation, and which are not fully handled.
Other exceptions are not caught by this variant;
to catch all exceptions, use try from Control.Exception. |
