Archived from the original on 20 February Haskell has a strongstatic type system based on Hindley—Milner type inference. Clean is a close, slightly older relative of Haskell. GHC hxskell98 noted for its rich type system incorporating recent innovations such as generalized algebraic data types and type families.
Monads are defined as ordinary datatypes, but Haskell provides some syntactic sugar for their use. Archived from the original Gaskell98 on 10 February Retrieved from ” https: Retrieved 15 February Jan-Willem Maessen, inand Simon Peyton Jonesindiscussed problems associated with lazy evaluation while also acknowledging the theoretical motives for it.
Haskell is based on the semanticsgeport not the syntax, of the language Mirandawhich served to focus the efforts of the initial Haskell working group.
Haskell 98 Language and Libraries
Retrieved 6 May The Computer Language Benchmarks Game also highlights its high-performance haskell98 of concurrency and parallelism. Academic programming languages Educational programming languages Functional languages Haskell programming language family Literate programming Pattern matching programming languages Programming languages created in Statically typed programming languages.
Its principal innovation in this area naskell98 type classes, originally conceived as a principled way to add overloading to the language,  but since finding many more uses. Monads are a general framework that can model different kinds of computation, including error handling, nondeterminismparsing and software transactional memory.
The Swift language is the product of tireless effort from a team of language experts, documentation gurus, compiler optimization ninjas, and an incredibly important repoet dogfooding group reporg provided feedback to help refine and battle-test ideas. Retrieved 9 February Perl Foundation Perl 6 Wiki.
A series of languages inspired by Haskell, but with different type systems, have been developed, including:.

It is a purely functional languagewhich means that functions generally have no side effects.
Retrieved 23 April Java virtual machine JVM based:. There have been many Haskell variants produced, exploring new language ideas, including:.
A distinct construct exists to represent side effects, orthogonal to the type of functions. The committee’s purpose was to consolidate existing functional languages into a common one to serve as a basis for future research in functional-language design. Archived from the original on 21 January An implementation of an algorithm similar to quick sort over lists, where the first element is taken as the pivot:.
