Description:
composable, streaming, and efficient left folds
This library provides strict left folds that stream in constant memory, and you can combine folds using Applicative style to derive new folds. Derived folds still traverse the container just once and are often as efficient as hand-written folds. . This package provides a library for the Haskell programming language. See http://www.haskell.org/ for more information on Haskell.
