All editions of Ada have supported operator overloading, complex (rich) type definitions, generics, built-in concurrency, etc. It was overlooked for too long but seems to be getting attention and increased usage again. Ada provides ways of restricting the features you use (i.e., specify your own subset if you like). Its also scalable from very small to very large projects.
