You may want to express that, but for the implementation of the language those two situations are the same, because in the [] literal the ptr is null. So I think it's better for the programmer to not differentiate the two situations, because they are not different. If the programmer tells them apart, he/she is doing something bad in D, creating a false illusion. Bye, bearophile
