I do not agree, that this is the only way of great languages. Great languages in my opinion are those, that implement concepts in a way, that they compose well and enable you to do anything you want elegantly. With the concepts they implement, they give you an answer to any situation might come across, without forcing you to write tedious ugly code as a workaround for lacking facilities. Perhaps what you refer to are great ecosystems of programming languages?
