This might not be directly relevant here, but in general, I'd
steer clear of main() for such experiments. Due to its special
nature (several possible signatures, but the calling code in
druntime stays the same), there is quite a bit of extra magic
going on internally.
For example, you wouldn't normally find "xor EAX, EAX" in a
void-returning functions, as its purpose is to set the return
value to 0, which implicitly happens to make the void main() and
void main(string[]) variants conform to the "full" int
main(string[]) signature.
