They do have value semantics but can't represent uniqueness
because of missing move d-tor.
For example in C++ I can create a function that returns a
Texture class instance and be sure that it is the only one when
receiving it (because copying is disabled). Then I can always
safely release all resources related to this texture in objects
d-tor. In D I can't use struct for this because I would get
double-free in d-tor so a class instance has to be used instead.
You can disable postblit to make entity non-copyable:
