Hi, can you explain a bit more? The question is not entirely 
clear to me. Can you mixin a struct of type PublicName and just 
hide everything in there?

mixin template TypeX() {
     struct PublicName {
         private alias This = typeof(this);
         private struct Unique {
			This* _ptr;
		}
         private Unique _data;
         alias _data this;
     }
}

void main(string[] args) {
     mixin TypeX;
     PublicName helper;
     helper._ptr.writeln;
}

Cheers
