You could implement loops/recursion with goto, something like:

  const int end = 10;
  int i = 0;
  assert(i < end);
  
  begin:
  <do stuff>
  i++
  if(i < end)
    goto begin;
  
  // end

But it really should be done with normal `for()`, or `while()`, so i think it would make sense to diagnose those.
