Agreed. But it should still be possible to add the additive identity (The core
language drafted to support this):
constexpr int* ptr = nullptr;
constexpr int x = 0;
constexpr int* ptr2 = ptr + x;

Yes, we rely on that in initializer_list<>::end(), and clang rejects that.
I discussed that case with Jason and we think [expr.add] could be clarified -
do you have an existing issue number related to that?
