Look what I found

@error WTAF?

@NormanDunbar Exactly.

@error oh god I need to wash my eyes out with bleach now

@error

switches are just polyamorous gotos

@error@mastodon.bsd.cafe actually pretty cool xd

@error @brunoph I think I remember techniques like this were useful for faking multithreading to do things like background calculations.

I was not smart enough or too smart to do it this way.

@error Duff's device all over again. Nice!

@error /me sets mode = 3, chuckling

@_the_cloud Yeah, but if you click the link, they actually use default case there.

@error I'm calling the police

@error that's wild. I wonder how this would be treated by different formatters/style enforcers and if it would break

@error At the time this was written (for hardware & compilers were pre SSA) this could have been reasonable.

@error yup that's how Contiki implemented Protothreads initially:

@error That's super neat, I didn't know! I'll probably use this in my code at a some point...

@error this should be classified as an infohazard

@error

Three lines too many. I thought serious programmers were lazy.

@error It's an utter pain in the arse when writing a compiler too, and even worse is when goto gets involved.

@mikee I actually tried it. It works just fine to my surprise. But the clangd formatter gone mad:

@error @_the_cloud Only in the original example, not in the first two. I'd set it to 3 and chuckle too. I'm an FPGA guy, so I always think about else/default.
