synopsis:      Monads for free
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:
