Examples for how to and how not to implement logic in a circuit

[mitschabaude]

This was a recent example from discord: https://discord.com/channels/484437221055922177/1221916531181752420/1221916531181752420

It contains a "failed attempt" at implementing array.includes() in a circuit which I find very educational. I think collecting this and similar examples on a page would serve as a useful deeper introduction to circuit programming.
