OK, another version. No typeof and O(1), due to the fact that in the good case the common_type_helper must always be instantiated with the same T, so the number of template instantiations doesn't grow, it has a constant limit. The bad case will fail anyway, but it might need some instantiations before finding out. I hope that this solution is acceptable for you. Regards, Daniel
