Пакет hugs98: Информация

Hugs 98 is a functional programming system based on Haskell 98, the de facto
standard for non-strict functional programming languages. Hugs 98 provides an
almost complete implementation of Haskell 98, including:

* Lazy evaluation, higher order functions, and pattern matching.

* 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.

* An advanced polymorphic type system with type and constructor class
  overloading.

* All of the features of the Haskell 98 expression and pattern syntax including
  lambda, case, conditional and let expressions, list comprehensions,
  do-notation, operator sections, and wildcard, irrefutable and `as' patterns.

* An implementation of the Haskell 98 primitives for monadic I/O, with support
  for simple interactive programs, access to text files, handle-based I/O, and
  exception handling.

* An almost complete implementation of the Haskell module system. Hugs 98 also
  supports a number of advanced and experimental extensions including
  multi-parameter classes, extensible records, rank-2 polymorphism,
  existentials, scoped type variables, and restricted type synonyms.
