Every new language is an attempt to fix some problems in the existing languages but at the same time be simple to learn and use. But the problem-space of programming is very complex. So while a new language does something better than some existing languages the language designers do not foresee all problems that may arise in actual use. Maybe a way to proceed would be to have a common set of code which every new language would try to rewrite, and thus see how much better it is, or is not, than the existing ones. Comparative analysis.
