Hugs 98 is a functional programming system which provides an almost
complete implementation of Haskell 98.

  o Lazy evaluation, higher order functions, and pattern matching.
  o A wide range of built-in types, from characters to bignums, and lists
    to functions, with comprehensive facilities for defining new datatypes
    and type synonyms.
  o A polymorphic type system with type and constructor class overloading.
  o All of the features of the Haskell 98 expression and pattern syntax.
  o An implementation of the main Haskell 98 primitives for monadic I/O,
    with support for simple interactive programs, access to text files,
    handle-based I/O, and exception handling.
  o An almost complete implementation of the Haskell module system.
    Hugs 98 also supports a number of experimental extensions including
    multi-parameter classes, extensible records, rank-2 polymorphism,
    existentials, scoped type variables, and restricted type synonyms.
