What about sound types? And I think having dynamically sized arrays in the language rather than standard library is an improvement in general because it removes extra cognitive load. Same for "print()." It just makes the language easier to write. The same way we never really need to pass functions as arguments because we can always pass an object that is guaranteed to have that function defined for it via interfaces. This is what is generally done in Java and it is awful.
