It is fortunate in my humble opinion that the designers of D think otherwise. In my experience Eiffel is the worst of languages. I worked with Eiffel one project. It was very unsafe for a compiled language. It has covariant function arguments and covariant arrays! At least Java and D made only one mistake not two. It has problems of dynamic languages and problems of static languages but not many advantages of them. It is not surprising Eiffel is considered bad by my professors and also by people in the industry. Dee Girl
