Haskell-type language, implements ideas described in a 'A Theory of Overloading'. Compiles Chameleon to (plain) Haskell; can mix Haskell and Chameleon overloading. Descriptions, documents, downloads.

Dialect with instance of data fields (a generalization of arrays), useful for rapid prototyping of parallel algorithms, and parallel high-level system specification.

Extension for parallel and distributed programming, with combinators from concurrent constraint programming; computational parts of programs are expressed functionally, development was first for tightly coupled multiprocessors, evolved from Goffin.

A functional language that aims at the programming of reactive systems and parallel algorithms on distributed memory systems.

A Haskell extension for parallel programming built on top of the Glasgow Haskell compiler (GHC). Parallelism is identified using annotations (generally evaluation strategies), that are defined using only two extra primitives: par and seq.

Small interpreter for language based on Haskell report 1.2; experimental, more so for type classes. Haskell adopted some ideas of Gofer, but Gofer type class system is more flexible. Runs on DOS, Linux, Macintosh, Unix. Hugs predecessor.

Object-oriented Haskell extension, using a preprocessor, supports a form of inheritance via extended class and instance declarations. Descriptions, documents, source download, links.

A functional programming language (subset of the Haskell) and a compiler designed especially for teaching Haskell.

An interpreter for Haskell which runs on almost any platform. Primarily used for teaching.

Many files for Hugs Haskell interpreter: source code, documents.

Java bytecode generator backend for Glasgow Haskell Compiler (GHC), so one can build Java applets or applications via the Haskell language.

Light version of Haskell to interoperate with other languages in OO environments; runs on .NET (old version for JVM), supports ASP.NET, to embed functional code in webpages with C#. Has version of Glasgow Haskell Compiler using Mondrian for .NET system to compile Haskell for .NET.

A Haskell 98 compiler.

Object Haskell: Haskell conservatively extended with subtyping, monadic objects.

A parallel eagerly evaluated variant of Haskell with syntactic provisions for loops, barriers, and I- and M- structure storage.

Polytypic programming language; source files for compiler written in Haskell that compiles PolyP-code to Haskell; library of polytypic functions written in PolyP, some examples, documents, downloads.

Haskell 98 extension allowing type-safe compile time metaprogramming, with Haskell, as the manipulating language and the language being manipulated.

An optimizing compiler for Haskell, written in Haskell. Includes extensions for concurrency and heap & time profiling. [Open Source, BSD-like]

A compiler and interactive system for Haskell 1.4, unsupported for two years now.
