I had naïvely assumed the Minecraft Hour of Code was the first of many modules that continued onwards in the same direction, but was surprised to discover that the Designer and Adventurer modules are the only ones available. This led to a question I posed in /r/minecraft, and a brief reply that confirmed [1], that indeed there isn't something like Hour of Code that continues past the two modules.
Before I re-invent the wheel that someone else has already built because my Google-fu failed to reveal someone else's project that has already trod this path, has anyone else here built a simplistic syntax on top of a Python API library to Minecraft, and set it up in a simple REPL? Extras would be a pre-built world that acts as a platform for puzzles, and a Lispy syntax, but as long as I'm not duplicating someone else's efforts, I'll do what I can for my child.
