I legit didn’t want to believe my eyes that it takes half a second after each code change before the IDE realizes whether a given change was correct or not. Also, you need clean builds quite often and I even got a “type inference times out” error message once which I haven’t seen in any PL ever even though I did dabble with quite a few static languages with even wider reaching type inference.
Well this isn’t a runtime time language it’s a compile time language they’ve actually done some great work behind the scenes to enable live view debugging (Previews).
