I guess I shouldn't be surprised, but this is a bit of a jolt after using
let.
#include <stdio.h>
int main(int argc, char** argv) {
int i = i;
printf("%d\n", i);
return 0;
}

} i may not actually be allocated by the time it is read for the first time (i ^= i) -- the compiler might decide that stuff should be allocated (lazily) at initialization and not at declaration and since i is never initialized it might never be allocated. I can't find this in DA STANDARD right now, though, so correct me if I'm wrong.
