It warms my heart to see Ladder Logic on the list! For those who don't know, Ladder Logic is a language used in industrial control systems. I worked for Cutler-Hammer Automation a couple of lifetimes ago and ladder logic was the preferred means for programming industrial control units. I worked for a major utility after Cutler-Hammer and learned they used PLCs at all their power stations and used ladder logic to control plant operations. It's a niche world, but it's BIG in that niche!
