That's how many puzzle games work, so I'm pretty sure this can be done with programming languages just as well. It would need a good progression of examples/exercises, but I think that could even be better in some aspects. For one it enforces a certain quality for the code examples because they can't rely on any explanation. And it would be less ambiguous when covering more abstract concepts (my biggest difficulties in understanding OOP and interfaces for the first time were caused by misleading explanations).
