programming outside of a class is overrated though in my opinion. 
i've never seen a usecase for it in an object oriented language. 
Of course Kotlin can do this, which is good, but you can just 
create utility classes (i.e. `static class` in C#, `final class` 
in Java with a private ctor, or Kotlin `object`.)
