Yes, I agree. Either be consistent with the idea that the module 
is the boundary for encapsulation or not.

It is better to give priority to plugging the holes that prevent 
people from writing code than preventing the compiler from 
accepting ill-conceived programs.

The current D compiler accepts too many programs, but that can be 
fixed with a linter.
