--
-- This module provides overloaded functions, such as 'deepseq' and
-- 'rnf', for fully evaluating data structures (that is, evaluating to
-- \"Normal Form\").
--
-- A typical use is to prevent resource leaks in lazy IO programs, by
-- forcing all characters from a file to be read. For example:
--
-- > import System.IO
-- > import Control.DeepSeq
-- > import Control.Exception (evaluate)
-- >
-- > readFile' :: FilePath -> IO String
-- > readFile' fn = do
-- >     h <- openFile fn ReadMode
-- >     s <- hGetContents h
-- >     evaluate (rnf s)
-- >     hClose h
-- >     return s
--
-- __Note__: The example above should rather be written in terms of
-- 'Control.Exception.bracket' to ensure releasing file-descriptors in
-- a timely matter (see the description of 'force' for an example).
--
-- 'deepseq' differs from 'seq' as it traverses data structures deeply,
-- for example, 'seq' will evaluate only to the first constructor in
-- the list:
--
-- > > [1,2,undefined] `seq` 3
-- > 3
--
-- While 'deepseq' will force evaluation of all the list elements:
--
-- > > [1,2,undefined] `deepseq` 3
-- > *** Exception: Prelude.undefined
--
-- Another common use is to ensure any exceptions hidden within lazy
-- fields of a data structure do not leak outside the scope of the
-- exception handler, or to force evaluation of a data structure in one
-- thread, before passing to another thread (preventing work moving to
-- the wrong threads).

-- | 'deepseq': fully evaluates the first argument, before returning the

--
-- The name 'deepseq' is used to illustrate the relationship to 'seq':
-- where 'seq' is shallow in the sense that it only evaluates the top
-- level of its argument, 'deepseq' traverses the entire data structure
-- evaluating it completely.
--
-- 'deepseq' can be useful for forcing pending exceptions,
-- eradicating space leaks, or forcing lazy I/O to happen.  It is
-- also useful in conjunction with parallel Strategies (see the
-- @parallel@ package).
--
-- There is no guarantee about the ordering of evaluation.  The
-- implementation may evaluate the components of the structure in
-- any order or in parallel.  To impose an actual order on
-- evaluation, use 'pseq' from "Control.Parallel" in the
-- @parallel@ package.

-- | a variant of 'deepseq' that is useful in some circumstances:

-- > force x = x `deepseq` x
--
-- @force x@ fully evaluates @x@, and then returns it.  Note that
-- @force x@ only performs evaluation when the value of @force x@
-- itself is demanded, so essentially it turns shallow evaluation into
-- deep evaluation.
--
-- 'force' can be conveniently used in combination with @ViewPatterns@:
--
-- > {-# LANGUAGE BangPatterns, ViewPatterns #-}
-- > import Control.DeepSeq
-- >
-- > someFun :: ComplexData -> SomeResult
-- > someFun (force -> !arg) = {- 'arg' will be fully evaluated -}

-- 'Control.Exception.evaluate' in order to force deep evaluation
-- relative to other 'IO' operations:
--
-- > import Control.Exception (evaluate)

-- >
-- > main = do
-- >   result <- evaluate $ force $ pureComputation
-- >   {- 'result' will be fully evaluated at this point -}

  -- === Compatibility with previous @deepseq@ versions

  -- Prior to version 1.4.0.0, the default implementation of the 'rnf'

  -- @'rnf' a = 'seq' a ()@
  --
  -- However, starting with @deepseq-1.4.0.0@, the default

  -- more accurate auto-derived 'NFData' instances. If you need the
  -- previously used exact default 'rnf' method implementation
