Extensible language
From Wikipedia, the free encyclopedia
An extensible language is any high-level language that allows its user to modify or enrich its syntax in such a way that a person that does not know the base code cannot tell the customized content from the original.
Examples of extensible languages are: lisp, forth, Ada 95, Ada 2005 and C++.
