@error I don't think I ever would have tried to pass that off, myself, but I sort of admire the fact that, even though it's language abuse, it produces a predictable outcome. C has a lot of undefined behavior, but somehow, this isn't.

I think I tried to use Duff's Device in a project once, but my colleagues objected and made me change it. Or maybe I just explained Duff's Device to them and they were horrified. Like, "I don't know if I can trust that guy anymore" horrified. It was a long time ago.

This is interesting but it's not really saving a ton of time or code space. I think Duff's Device is probably more defensible.
