Hugs (interpreter)
Appearance
Hugs (Haskell User's Gofer System) is a bytecode interpreter for the functional programming language Haskell. It offers fast compilation of programs and reasonable execution speed. It also comes with a simple graphics library. Hugs is good for people learning the basics of Haskell, but is by no means a "toy" implementation. It is the most portable and lightweight of the Haskell implementations.
