+ -- runIOFastExit: makes exceptions raised by Main.main
+ -- behave in the same way as for a compiled program.
+ -- The "fast exit" part just calls exit() directly
+ -- instead of doing an orderly runtime shutdown,
+ -- otherwise the main GHCi thread will complain about
+ -- being interrupted.
+ --
+ -- Why (main >> return ()) rather than just main? Because
+ -- otherwise GHCi by default tries to evaluate the result
+ -- of the IO in order to show it (see #1200).
