araujo@gentoo.org Luis F. Araujo Dylan is an advanced, object-oriented, dynamic language which supports the rapid development of programs. When needed, the programmer can later optimize [his or her] programs for more efficient execution by supplying type information to the compiler. Nearly all entities in Dylan (including functions, classes, and basic data types such as integers) are first class objects. Additionally Dylan supports multiple inheritance, polymorphism, multiple dispatch, keyword arguments, object introspection, and many other advanced features.
