I wonder how it would be if we had an error or warning for 
something like this. For example displaying a message forcing the 
use of the word "static" and initialize with "static this" when 
expecting static initialization or construct for new instances.

Before someone points out: https://dlang.org/spec/class.html

Yes I know, but unfortunately this mistake as Basile noted as 
"classic", is very common.
