Beyond that, I go through the languages too fast this time to be worth linking to individual ones. I also buried other comments and issues throughout the source that I didn't discuss out loud, in case the other matters are of interest to anyone.
Languages include: Python, Java, Go, C++, TypeScript, PHP, C#, C, HTML, Swift, Scala, Dart, Rust, and Kotlin. Also a tiny bit of discussion on Objective-C.
