I see from the voting results (Future RPG IV enhancements) that I/O
to ext-desc struct got more than 100 votes, although I didn't spend
$2 on it :-).

I still can't see that what you describe differs much (if anything at all)
from the current capability of the language, as the example I've used below:

D rfli04o       e ds                  extname(pfli04) prefix(o_)
D rfli04n       e ds                  extname(pfli04) prefix(n_)
