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.
