%description
|
|
Free monads are useful for many tree-like structures and domain specific
|
|
languages.
|
|
|
|
If 'f' is a 'Functor' then the free 'Monad' on 'f' is the type of trees whose
|
|
nodes are labeled with the constructors of 'f'. The word "free" is used in the
|
|
sense of "unrestricted" rather than "zero-cost": 'Free f' makes no constraining
|
|
assumptions beyond those given by 'f' and the definition of 'Monad'.
|
|
As used here it is a standard term from the mathematical theory of adjoint
|
|
functors.
|
|
|
|
Cofree comonads are dual to free monads. They provide convenient ways to talk
|
|
about branching streams and rose-trees, and can be used to annotate syntax
|
|
trees. The cofree comonad can be seen as a stream parameterized by a 'Functor'
|
|
that controls its branching factor.
|
|
|
|
More information on free monads, including examples, can be found in the
|
|
following blog posts: <http://comonad.com/reader/2008/monads-for-free/>
