Right. One of the benefits of destroy is that it nulls the
reference. Once you destroy it, you aren't supposed to use it
again*. The zombie is kept around until the GC reaps it to
protect against dangling pointers (somewhat), but you still
aren't actually supposed to reuse it.
* If you really want to you can cheat by making a separate local
variable to hold it before destroy it... destroy only nulls the
variable you pass in, but I do not recommend doing this. Instead,
you should reconstruct the object, even if implementing an object
pool or something.
I use writeln("Address of s ", &s) to print the address, not
sure if that is correct though.
that gives you the address of the local variable, not the
reference. For address of the reference, try `cast(void*) s`.
An Object in D is like an Object* in C++. So when you & it, you
get a pointer to a pointer.
