You've said this in August 2004, and were given your example
written in the (technically more powerful) Spitbol pattern matcher

Try this:

template <int x> int more(int y) { return x + y; }

int main(void)
{
  int result = 0;
  for (int p = 0; p < 100; ++p) { result += more<p>(5); }
  return result;
}
