In my experience null and empty in DTOs usually play the same

The distintion is really important: NULL is a valid value

why?
Because an empty string is, by default, represented by an empty
slice of the null pointer.
I don't program in D. I just read from time to time posts in the
D forum because of the good quality of what people write. So, I'm
not proficient in D, but in general internals should not boil up

In a relational database, `NULL` is not the same that `""`... and
`NULL` is not the same that `0`. Are semantically different and
there are database invariants (like fore
