'''XL''' stands for eXtensible Language. It is the first and so far the only [[computer]] [[programming language]] designed to support [[concept programming]].<ref>{{cite news|url=httphttps://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| accessdate=2010-02-03}}</ref>

XL features programmer-reconfigurable syntax and semantics. Compiler ''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.
