[ontologiae]

There's an interesting language strongly influenced by Self : Lisaac ( http://www.lisaac.org ). Lisaac is a purely prototype language extending the Self's prototype paradigm with extremely good performance (close to C code, biggest part of the research around this language was about high performance code generated by the compiler).

For instance, you can define a dynamic inheritance : your inheritance can be defined by a function which return an object - so, a prototype - among several.

The author of this language explain me that Self was one of the most important day in his life ;-)
