I had a dream last night about #programming ChaCha20.

> "Here's your 512-bit state array."

> "Don't forget your quarter round."
> ...
> "Not 20 quarter rounds, 80 you nitwit!"
> ...
> "Yes, increment the counter."
> ...
> "Stop using the all-zero key."
> ...
> "An all-zero nonce isn't any better."
