  2. Haskell - Wikipedia

    en.wikipedia.org/wiki/Haskell

    The first revision, named Haskell 2010, was announced in November 2009 [2] and published in July 2010. Haskell 2010 is an incremental update to the language, mostly incorporating several well-used and uncontroversial features previously enabled via compiler-specific flags. Hierarchical module names.

  3. Functor (functional programming) - Wikipedia

    en.wikipedia.org/wiki/Functor_(functional...

    Applying fmap (+1) to a binary tree of integers increments each integer in the tree by one.. In functional programming, a functor is a design pattern inspired by the definition from category theory that allows one to apply a function to values inside a generic type without changing the structure of the generic type.

  4. Map (higher-order function) - Wikipedia

    en.wikipedia.org/wiki/Map_(higher-order_function)

    In Haskell, the polymorphic function map :: (a -> b) -> [a] -> [b] is generalized to a polytypic function fmap :: Functor f => (a -> b) -> f a -> f b, which applies to any type belonging the Functor type class. The type constructor of lists [] can be defined as an instance of the Functor type class using the map function from the previous example:

  5. Foreign function interface - Wikipedia

    en.wikipedia.org/wiki/Foreign_function_interface

    [8] [9] Common Lisp; Compiled Native Interface (CNI), alternative to JNI used in the GNU compiler environment. One of the bases of the Component Object Model is a common interface format, which natively uses the same types as Visual Basic for strings and arrays. D does it the same way as C++ does, with extern "C" through extern (C++)

  6. Haskell features - Wikipedia

    en.wikipedia.org/wiki/Haskell_features

    Concurrent Haskell is an extension to Haskell that supports threads and synchronization. [7] GHC's implementation of Concurrent Haskell is based on multiplexing lightweight Haskell threads onto a few heavyweight operating system (OS) threads, [8] so that Concurrent Haskell programs run in parallel via symmetric multiprocessing. The runtime can ...

  7. Foreach loop - Wikipedia

    en.wikipedia.org/wiki/Foreach_loop

    In computer programming, foreach loop (or for-each loop) is a control flow statement for traversing items in a collection. foreach is usually used in place of a standard for loop statement.

  8. Comparison of programming languages by type system

    en.wikipedia.org/wiki/Comparison_of_programming...

    This is a comparison of the features of the type systems and type checking of multiple programming languages.. Brief definitions A nominal type system means that the language decides whether types are compatible and/or equivalent based on explicit declarations and names.

  9. Language interoperability - Wikipedia

    en.wikipedia.org/wiki/Language_interoperability

    Mutability becomes an issue when trying to create interoperability between pure functional and procedural languages. Languages like Haskell have no mutable types, whereas C++ does not provide such rigorous guarantees. Many functional types when bridged to object oriented languages can not guarantee that the underlying objects won't be modified.
