It's better shown than told. Just see this: 7 minutes of Pharo Smalltalk for Rubyists - https://www.youtube.com/watch?v=HOuZyOKa91o https://www.youtube.com/watc

  I watched the whole video, thank you for sharing! The bit towards the end (around 5 min mark I believe) where he gives the IDE (is that what you call it?) an input + desired output and asks it what message would produce the result he wants is pretty damn cool. The rest of it is "interesting" I suppose. I can imagine that, at the time, this sort of interactive/live visual environment was revolutionary. This would be 1972-1990's I think, and during those early years there was nothing even remotely similar, right? Towards the end Rapid Application Development (RAD) IDE's would start taking hold and then came the Pascal-powered heydays for a bit. I think that maybe just due to familiarity bias, I still prefer a text-based IDE which has hot-reloading and live eval results. Something pretty neat I use personally is an extension called "Quokka" which places the results of each line next to them, live as you edit (similar to a REPL) https://quokkajs.com/ https://quokkajs.com/ Jetbrains IDE's have a similar thing with "Worksheets" for languages like Kotlin, Python, Scala, and likely a few others. (Also "Metals" extension in VS Code can do this for Scala incredibly well)
