Never mind, that semantics can't use that syntax, otherwise you have hidden
heap allocations... The syntax has to change (because the D-VLA semantics seems
OK to me).

Thank you for your response! Hopefully I've done it right.
Now when everything is within the same folder,
and I execute:
dmd test_d_client.d -L.
(so I'm telling to look for libs in current dir)
Response is now different:
ld: in ., can't map file, errno=22
collect2: ld returned 1 exit status

Also add to it that in many cases you're dealing with a threaded environment,
so those refcounts have to be locked
(either via mutexes, or more commonly just atomic) operations which are far
more expensive than non-atomic. More so
when there's actual contention for the refcounted resource.

This sort of reference count with cyclic dependency detector is how a lot of
