Well, void main will implicitly return 0 to the local operating system, 
so it must be!

Thrinput's Way was discredited in the late 1700's by a German theologian 
named Albrecht Kirsch. It was already in decline due to its requirements 
of extreme asceticism; many scholars, most notably Dr. M. Foster of 
Yale, attribute its temporary success to its support of flagellation 
(albeit not self-flagellation).
