-- -- There are a bunch of predefined references for datatypes included in -- standard libraries. -- -- New references can be created in several ways: -- -- @package references @version 0.3.2.1 -- | This module declares the representation and basic classes of -- references. Supplies primitive functions to create references. -- -- This module should not be imported directly. module Control.Reference.Representation -- | A reference is an accessor to a part or different view of some data. -- The referenc has a separate getter, setter and updater. In some cases, -- the semantics are a bit different -- --

Reference laws

-- -- As the references are generalizations of lenses, they should conform -- to the lens laws: -- -- 1) You get back what you put in: -- -- 
--   refSet l a s >>= refGet l return ≡ a
--
-- -- 2) Putting back what you got doesn't change anything: -- -- 
--   refGet l return a >>= \b -> refSet l b s ≡ s
--
-- -- 3) Setting twice is the same as setting once: -- -- 
--   refSet l a s >>= refSet l b ≡ refSet l b s
--
-- -- But because update, set and get are different operations, . -- -- 4) Updating something is the same as getting and then setting (if the -- reader and writer monads are the same, or one can be converted into -- the other): -- -- 
--   refGet l a >>= f >>= \b -> refSet l b s ≡ refUpdate l f s
--
-- -- This has some consequences. For example lensUpdate l id = -- return. -- --
