C# example (silly, but it demonstrates the point).

The problem is not so much D, but that C++/Java/C# programmers, 
and many from other languages (Go, Rust....) will expect private 
to mean private...not private..depending on....

They will expect the interface they defined, to be respected.

Then they'll start asking..wtf!@$#?   .. and end up in long 
threads like this one, trying to work out why the world is upside 
down (or seems like it).

And don't get me started on public being the default in D .. 
cause at some point..I gotta get some sleep.

         //p.name = "King Joffrey"; // dude. this is private!
     }

public class Person
{
     private string name;
     public string getName() { return name; }
