:content
Stores an internal reference to another `DValue`. Most unit code should not need to create references directly; normal reads and writes generally follow existing references automatically.


:example
DValue target;
target.set("original");
DValue ref;
ref.set_reference(&target);
print(ref.deref().to_string(), "\n");
