'''XL''' ("'''eXtensible Language'''") is the first computer [[programming language]] designed to support concept programming.<ref>{{cite news|url=https://www.theregister.co.uk/2008/01/16/concept_programming |title=Dip into Concept Programming |first=Phil |last=Manchester |publisher=[[The Register]] |date=2008-01-16| access-date=2010-02-03}}</ref>

XL features programmer-reconfigurable [[Syntax (programming languages)|syntax]] and [[Semantics (computer science)|semantics]]. Compiler [[Plug-in (computing)|plug-ins]] can be used to add new features to the language. A base set of plug-ins implements a relatively standard [[imperative programming|imperative language]]. Programmers can write their own plug-ins to implement application-specific notations, such as [[derivative|symbolic differentiation]], which can then be used as readily as built-in language features.

There are projects that exploit similar ideas to create code with higher level of abstraction. Among them are:

* [[Intentional programming]]

* [[Language-oriented programming]]

* [[Literate programming]]

* [[Model-driven architecture]]
