Similar to catch, but returns an Either result which is (Right a) if no exception of type e was raised, or (Left ex) if an exception of type e was raised and its value is ex. If any other type of exception is raised then it will be propagated up to the next enclosing exception handler. 
try a = catch (Right `liftM` a) (return . Left)

Like try, but rethrows async exceptions.
