hey, @grazer
It would be cool if there were a feature where you could create an entire map out of blocks inside of a block and also load the map. And all the behaviors inside the blocks of the map could be disabled or enabled by the block host. So when you spawn or load the map, the behaviors would function or not. This could be used to make a map generator for rogue games or dungeon games or survival games. So it could be 2x2 to 32x32 blocks long.
