Object Functional

Combining ObjectOrientedProgramming and FunctionalProgramming.

ObjectFunctional languages can be classified by how they handle state and I/O:

• in "hybrid" ObjectFunctional languages, the core semantics is imperative, and support for FunctionalProgramming is added, but any function can potentially have SideEffects.
• in "pure" ObjectFunctional languages, the core semantics is functional (i.e. guarantees ReferentialTransparency), and imperative aspects of ObjectOrientedProgramming are supported using MonadicProgramming, UniquenessTypes, etc.
  • not impossible: a "pure-hybrid" where procedures and functions are separate types and functions may not have SideEffects (DeeLanguage allows kind of this).

Hybrid ObjectFunctional languages:

• NiceLanguage
• PythonLanguage
• RubyLanguage
• CommonLisp
• DeeLanguage
• DylanLanguage
• GooLanguage
• NeedleLanguage
• ObjectiveCaml
• GroovyLanguage (maybe?)
• ScalaLanguage
• NemerleLanguage
• OzLanguage
• EeLanguage
• CeeSharpLanguage (esp. 3.0)
• CeePlusPlus with additions e.g. FunctoidsInCpp and the BoostLibraries.

Pure ObjectFunctional languages:

• OhHaskell

Patterns

• ObjectFunctionalPatterns

It is possible to use some ObjectFunctionalPatterns for simple ObjectOrientedProgrammingLanguages.
