switch statements
switch statements require you to exhaustively consider all relevant or possible inputs (if you don’t rely on default).
Interestingly, the notion that switch statements can require a default is reflective of the truth to the idea that when the stakes get high, we all fall back to our default level of training or function. This has global applications to our functionality and, by extension, the inputs (things,people/their methods,contexts) in our lives as well
So if you have ever dealt with PLCs beyond the basics you know that timing/parallelism is a clusterfuck of misery and pain until you get to the point where you can master it.
I am pretty decent at keeping multiple things going as a result.
