This extension was specified in an addendum to Haskell 98 and was in practice universally used. The foreign function interface (FFI) allows bindings to other programming languages. Only bindings to C are specified in the Report, but the design allows for other language bindings.
The Glasgow Haskell Compiler (GHC) is a native or machine code compiler for the functional programming language Haskell. [5] It provides a cross-platform software environment for writing and testing Haskell code and supports many extensions, libraries , and optimisations that streamline the process of generating and executing code.
Hugs deviates from the Haskell 98 specification [2] in several minor ways. [3] For example, Hugs does not support mutually recursive modules. A list of differences exists. [4] The Hugs prompt is a Haskell read–eval–print loop (REPL). It accepts expressions for evaluation, but not module, type, or function definitions.
Gofer (Good for equational reasoning) is an implementation of the programming language Haskell intended for educational purposes and supporting a language based on version 1.2 of the Haskell report. It was replaced by Hugs. [1] Its syntax is closer to the earlier commercial language Miranda than the subsequently

It is dependent on Glasgow Haskell Compiler (GHC), using a modified form of the HsParser (written in Happy) parser for Haskell included in GHC. [6] Its lightweight markup is based on IDoc's. [6] Haddock is contained in the Haskell Platform. It is used by the GHC, Gtk2Hs and HTk projects, [7] as well as xmonad. [citation needed]
Concurrent Haskell is an extension to Haskell that supports threads and synchronization. [7] GHC's implementation of Concurrent Haskell is based on multiplexing lightweight Haskell threads onto a few heavyweight operating system (OS) threads, [8] so that Concurrent Haskell programs run in parallel via symmetric multiprocessing. The runtime can ...
