closest C-like equivalent (and thus something to emulate) is:

main() {

 int i=0;
 do {
   printf("%d\n",i);
   i++;
 } while(!(i>2));
}

which says:

$ ./a.out 
0
1
2

I suspect when I implemented that I was thinking of the i++ being after 
the condition check, rather than before, but consistency suggests that I 
was wrong.
