You should almost never use `ref string`. Just use plain `string`.

In fact, ref in general in D is a lot more rare than in languages 
like C++. The main reason to use it for arrays is when you need 
changes to the length to be visible to the caller... which is 
fairly rare.

nope, an object isn't created there at all. you should use `new 
C`.
