Return types Memes

The evolution of main function signatures, from basic to absolutely transcendent. Starting with the peasant-tier function main() , ascending through int main() (slightly more enlightened), reaching void main() (controversial but galaxy-brained), and finally achieving divine consciousness with U0 main() . For the uninitiated: U0 is HolyC's void type, the programming language created by the late Terry Davis for TempleOS—an entire operating system built by one man who claimed to be building God's temple. U0 represents the ultimate return type: nothing, because when you're programming for divine purposes, what even is a return value? You don't return to the OS, you return to the heavens. The ascension makes perfect sense: regular developers use functions, smart developers return integers, galaxy brains use void, but only the truly enlightened use U0 and compile their code in 640x480 16-color glory while talking directly to God through random number generators.
