Hugs deviates from the Haskell 98 specification in several minor ways. For example, Hugs does not support mutually recursive modules. Hugs was originally deveolped by Mark P Jones, a professor at Portland State University.
The Hugs prompt (a Haskell REPL) accepts expressions for evaluation, but not module, type or function definitions. Hugs can load Haskell modules at start-up.
