Description:
Monads for free; profiling libraries
Free monads are useful for many tree-like structures and domain specific languages. . A Monad n is a free Monad for f if every Monad homomorphism from n to another monad m is equivalent to a natural transformation from f to m. . Cofree comonads provide convenient ways to talk about branching streams and rose-trees, and can be used to annotate syntax trees. . A Comonad v is a cofree Comonad for f if every Comonad homomorphism another comonad w to v is equivalent to a natural transformation from w to f. . This package provides a library for the Haskell programming language, compiled for profiling. See http://www.haskell.org/ for more information on Haskell.
