Is great.... except the lack of support for writing your own functions. Except you can simulate it with hacks, which are confusing to kids. My son did SB at school, and the code they produced was a mess because they couldn't structure things well when they needed repeated, but slightly different things to happen, they end up copy pasting, then they have a problem and have to track down all the copy pastes, etc
