Description:
free monads; profiling libraries
This package provides datatypes to construct Free monads, Free monad transformers, and useful instances. In addition it provides the constructs to avoid quadratic complexity of left associative bind, as explained in: . Janis Voigtlander, Asymptotic Improvement of Computations over Free Monads, MPC'08 . This package provides a library for the Haskell programming language, compiled for profiling. See http://www.haskell.org/ for more information on Haskell.
