Dylan programming language

Dylan is a dynamic programming language created by a group within Apple Computer. It was originally intended for use with Apple's Newton computer but their implementation did not reach sufficient maturity to ship it as a product (though it did ship as a technology demonstration). However, the language design was intriguing enough that at least one company and a university implemented compilers and development environments for Dylan that were quite good.

The Dylan language is notable for being purely object-oriented: every value is an object.
