Many people here are using Smalltalk for years. Just because you have been silent for some time doesn’t mean everybody will forget about you :)

First, there are no good definitions of what is an object oriented language and what is a functional language. Thus, languages like C++, C#, Java are being considered object oriented. But their object orientation is not the same like Smalltalk’s. The same problem exists in the functional language world: Some consider LISP being functional, some deny that. Second, for some years I am constantly seeking for „the best“ language to solve my problems in. Alas I wasn’t successful yet and don’t expect to be successful in the future. Every programming paradigm has its strengths and weaknesses when it comes to real world problems. So in my eyes it is best to know the different programming paradigms and its representative languages in order to be able to choose the best fitting language for your problem at hand. Third, there have been many attempts to create multi-paradigm languages (like C++, C#, Java, Scala, …). The idea behind is simple: combine the best characteristics. In my eyes all of them failed because what always have been created is Frankenstein’s monster. When you combine paradigms you will may get some advantages of all but sure you will get a lot of additional complexity. Fourth, it has been said many times before: What makes Smalltalk so nice is not only the language. It’s the whole system: the language, duck typing, the image (object world), the tools, the VM, the simplicity, the elegance, … And last but not least the communities around. Regards Andreas PS: If you are interested in functional programming and don’t like static typing you should have a look at Clojure. It has some nice ideas about how to deal with state concurrently. > Thanks > > Kjell E Godø > > > > > > > > > > (((((((((( Maybe Smalltalk should be called Statewalk > > as in yak it up fuzz ball. )))))))))) >
