Thanks for the encouragement! Yes, I've seen the English dubbing, as I've watched the few videos or so. It seems like an interesting language, and I really like the idea of interactive programming systems. It's similar to what I use and the languages I am interested in, but I haven't given a Smalltalk system proper learning time. I feel it's an area of computer science that has not received much attention. If programming languages and their environments were more interactive and gave better feedback, then I feel I don't need all sorts of fancy stuff like dependent types, which really seem to excite people. If the system's interactability and feedback is good enough, I, the programmer, can make the right decisions, which is the primary challenge when programming.
