A modern programming language that makes developers happier.

kotlinlang

In <https://github.com/EventFahrplan/EventFahrplan|this multi-modules Android project> I am enabling <https://kotlinlang.org/docs/reference/whatsnew14.html#explicit-api-mode-for-library-authors|explicit API> mode in <https://github.com/EventFahrplan/EventFahrplan/commit/8dfe48a18694ead7672fa2d4dc0ad173c9297748|this commit>.
The compiler forces me to change a few classes and methods (adding `public`), all in one module.
:question: Why are all *other modules not affected* although they do not declare `public` modifiers for their classes and methods?
