This is a pure banger feature, one of the best usability improvements of the new Castagne. State Calls were a huge feature in the previous version, and you could use it to create behavior either by extending a state or through composition. Interally both were the same, but I added warnings and _Helper() to distinguish between the two. You could alter internal defines, but it was a bit janky.
