module Futures

-- | Abstraction over a pattern where you delegate an IO action to be
--   executed on another thread, but are still interested in processing its
--   result some time later on. In the meantime you can execute other
--   actions. IOW, it is an implementation of asynchronous programming
--   pattern.
--   
--   Another way to look at future is as on an evaluate-once computation.
data Future a

-- | Fork a thread to execute the computation on and produce a future,
--   which will provide its results.
--   
--   The IO action must not throw exceptions! If you want to transfer them,
--   wrap it in <a>try</a>.
fork :: IO a -> IO (Future a)

-- | Block waiting until the future result is available.
