It's an interesting idea, but I disagree: I think you remember things much easier if you write them out (and have to make them compile/execute) yourself. If I read some code in a language I haven't encountered before, I find I don't absorb any of the little details of syntax. Moreover, I think it makes sense to expose learners to the fun of programming early. And to me that means seeing something that you wrote running.
