Then just add `static class`, as it will provide a solution 
without robbing you of another solution. You still can put 
symbols in a module even if `static class` is a thing. `static 
class` doesn't break existing solutions, it just adds things on

Good. Now, let people have OOP and "everything is a class" if 
they want to.

I think it's better to have a widespread commonly known solution 
than hacks that you have to specifically look for. D is guilty 
with having too many hacks that you have to specifically learn
