The Computer Language Benchmarks Game also highlights its high-performance implementation of concurrency and parallelism. Retrieved 23 April Of course, it also greatly benefited from the experiences hard-won by many other languages in the field, drawing ideas from Hqskell98, Rust, Haskell, Ruby, Python, CCLU, and far too many others to list. A series of languages inspired by Haskell, but with different type systems, have been developed, including:.

A distinct construct exists to represent side effects, orthogonal to the type of functions. Archived from the original on 20 February Monads are defined as ordinary datatypes, but Haskell provides some syntactic sugar for their use. Miranda was the most widely used, but it was proprietary software.

The committee expressly welcomed creating extensions and variants of Haskell 98 via adding and incorporating experimental repoort. In Februarythe Haskell 98 language standard was originally published as The Haskell 98 Report.

This has been addressed [70] by the release of the Stackwhich manages cabal, to do the work in a build. Retrieved 6 May Haskell features a type system with type inference [30] and lazy evaluation. At the conference on Functional Programming Languages and Computer Architecture FPCA ’87 in Portland, Oregonthere was a strong consensus that a committee be formed to define an open standard for such languages. The construct that represents side effects is an example of a monad.

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.

Wearing the hair shirt: Archived from the original PDF on 10 February Ben Lippmeier designed Disciple [66] as a strict-by-default lazy by explicit annotation dialect of Haskell with a type-and-effect system, to address Haskell’s difficulties in reasoning about lazy evaluation and in using traditional data structures such as mutable arrays.
