1. fromException :: Exception e => SomeException -> Maybe e

   ghc-internal	GHC.Internal.Control.Exception

   No documentation available.

2. mapException :: (Exception e1, Exception e2) => (e1 -> e2) -> a -> a

   ghc-internal	GHC.Internal.Control.Exception

   This function maps one exception into another as proposed in the paper "A semantics for imprecise exceptions".

3. onException :: IO a -> IO b -> IO a

   ghc-internal	GHC.Internal.Control.Exception

   Like finally, but only performs the final action if there was an exception raised by the computation.

4. toException :: Exception e => e -> SomeException

   ghc-internal	GHC.Internal.Control.Exception

   toException should produce a SomeException with no attached ExceptionContext.

5. data ArithException

   ghc-internal	GHC.Internal.Control.Exception.Base

   Arithmetic exceptions.

6. data ArrayException

   ghc-internal	GHC.Internal.Control.Exception.Base

   Exceptions generated by array operations

7. data AsyncException

   ghc-internal	GHC.Internal.Control.Exception.Base

   Asynchronous exceptions.

8. data FixIOException

   ghc-internal	GHC.Internal.Control.Exception.Base

   The exception thrown when an infinite cycle is detected in fixIO.

9. FixIOException :: FixIOException

   ghc-internal	GHC.Internal.Control.Exception.Base

   No documentation available.

10. data IOException

    ghc-internal	GHC.Internal.Control.Exception.Base

    Exceptions that occur in the IO monad. An IOException records a more specific error type, a descriptive string and maybe the handle that was used when the error was flagged.
