Look what I found

@error gloop, arfle, barfle says it all.

@error ha! Thanks for testing!

@error it's beautiful

@error reminds me of Duff's Device for abitrary length byte copy using the switch as an index into an architecture-appropriate unrolled loop https://en.wikipedia.org/wiki/Duff%27s_device

@vaporeon_ please don't

@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.

@error @TomDuff, call your office...

@mmu_man @error Never heard of these before; thank you!

@WesternInfidels It produces warning, so I personally won't use it. But it looks beautiful

@ewhac @error Insane. No one in his right mind calls functions arfle and barfle.

@error time to see who at my workplace I can aggravate the most

@error yes

@error this is devious and i love it

@error musl does this in its printf implementation: https://git.musl-libc.org/cgit/musl/tree/src/stdio/vfprintf.c#n597

@error wow it does not even -Wextra the nested labels

@gloriouscow @error the important part is the boundaries tbh

@error

May I offer you more cursed code

@error
This is much more readable to me than the original screenshot. The font inconsistency had me trying to figure out what the base code was and what was just an annotation
