In Swift it's even worse. All symbols in neighbor files are available. No imports.

Also in Java, and one of the (few) features they added was “module imports” (https://docs.oracle.com/en/java/javase/24/language/module-im...). I’m curious why, my guess is that it’s for beginners and scripts (same with “unnamed classes and instance main” (https://docs.oracle.com/en/java/javase/21/language/implicitl...)).
