@hamishtpb I've been learning Forth for fun recently, it's a fun brain exercise to figure out how to make the data flow smoothly from one word to the next. I think going through Easy Forth (https://skilldrick.github.io/easyforth/) was quite helpful for me, although Starting Forth (https://www.forth.com/starting-forth/) was more insightful, albeit a longer read.
@anjune@hamishtpb Well, there's Factor (https://factorcode.org/) which is kind of like a modern Forth, but it's not really a Forth. GForth and SwiftForth are the "modern" Forths I suppose. Plenty of other smaller Forths out there too because they are so easy to implement.
