Stream Fusion

About

Data.List.Stream provides the standard Haskell list data type and api, with an improved fusion system, as described in the papers Stream Fusion and Rewriting Haskell Strings. Code written to use the Data.List.Stream library should run faster (or at worst, as fast) as existing list code. A precise, correct reimplementation is a major goal of this project, and Data.List.Stream comes bundled with around 1000 QuickCheck properties, testing against the Haskell98 specification, and the standard library. This project is also know as Ticket 915.
