The following is even more "expected". ;) Subtract zero from -1 and you 
get size_t.max.

void main() {
   int[] arr;
   int i = -1;

   auto u = (i - arr.length);    // -1 - 0

   assert(u == size_t.max);                   // the surprise
   static assert (is (typeof(u) == size_t));  // the reason
}
