| Description |
| Top-level IO actions want to catch exceptions (e.g., forkIO and
mainIO) and report them - topHandler is the exception
handler they should use for this.

| runIO :: IO a -> IO a |
| runIO is wrapped around main by TcModule. It is also wrapped
around every foreign export and foreign import "wrapper" to mop up
any uncaught exceptions. Thus, the result of running
exitWith in a foreign-exported function is the same as
in the main thread: it terminates the program.
|
|
| runNonIO :: a -> IO a |
| The same as runIO, but for non-IO computations. Used for
wrapping foreign export and foreign import "wrapper" when these
are used to export Haskell functions with non-IO types.
