 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.


It's bad, when the language is driven by the implementation of a "reference"
compiler by the copyright holder. This way compiler bugs and tricks become a
language standard. See the story of VP7 codec.
