> Just to note though: Javascript in fact doesn't require representing objects as hash tables. For example, the V8 javascript engine represents objects as instances of classes, more or less exactly how C++ would do it (the build the class definitions automatically in the background.) That sounds like what Self does, too. See the excellent paper, "An Efficient Implementation of SELF" (http://selflanguage.org/documentation/published/implementation.html http://selflanguage.org/documentation/published/implementati...). The Self bibliography page (http://selflanguage.org/documentation/published/index.html http://selflanguage.org/documentation/published/index.html) has a lot of other content applicable to dynamic languages in general, too.
