[PATCH] D43159: Modernize: Use nullptr more.

[Eric Fiselier via Phabricator via cfe-commits]

EricWF added a comment.

So my main concern with this patch is that `nullptr` is actually  `#defined`'ed in C++03 mode. That definition comes from the `__nullptr` header, and therefore we would need to add that header to each include which uses it. Which kind of sucks.
