Ha, took me two minutes to make that code sandbox. Can you tell me at least if it is possible in Nue to create something functional like this and how? Or is it just a bunch of macro with some weird imperatives inside usual XML syntax? I really want to see 4 lines of code doing the same thing 2x faster :D
