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 SideEffect''''''s.
* 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 SideEffect''''''s (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 ObjectOrientedProgrammingLanguage''''''s.
