Dylan is a functional, object-oriented, dynamic programming language with four goals: high performance, rapid prototyping, ease of use, and seamless support for libraries coded in C. It is an interesting hybrid system. Linguistically, and syntactically it is rather C-like. At its base, it is very functional and Lisp-like, using Lisp functional aspects and compiler technology, but with no Symbolic EXPressions (SEXP, S-exp), or ability to manipulate programs as lists. Everything is an object, so it is a pure object-oriented language. It has many other interesting, useful traits.
