[Nfd-dev] code style rule 3.20

[Davide Pesavento]

There is no such thing as std::nullptr.

In C++11 nullptr (without std) is a language keyword, it is *not* part of
the standard library. The type of nullptr, on the other hand, is
std::nullptr_t, and is part of the standard library.

That being said, I agree with the proposal.

Thanks,
Davide
