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.
