It seems to stick to 0, though. Is that because its numbers is
determined at shipout only? But then it's useless, since after shipout
you can't retrieve it... I suppose the object number is reserved in
advance, but the field here isn't correctly updated? See:
\output{
\directlua{
local dest = tex.box[255].head.next.head
while not(dest.id == 8 and dest.subtype == 19) do
dest = dest.next
end
texio.write_nl(dest.objnum)}
\shipout\box255
}
abc \pdfdest num 1 fitr

This prints 0, even though 0 is an illegal object number (and the
destination is in object 5 anyway).
Also, totally unrelated: with object streams, pdfTeX signals the
objects' numbers in a comment:
% 2 0 obj
...
% 8 0 obj
...
% 25 0 obj
...
LuaTeX does so too, but the comment is at the end of the last line of
the previous object, which is quite unreadable:
% 2 0 obj
... % 8 0 obj
... % 25 0 obj
...
I think somebody forgot a carriage return, or is that on purpose?
Best,
