Re: [std-proposals] delete p = nullptr;

As a semi-serious/semi-joking suggestion in existing C++ `delete
std::exchange(p,nullptr);`.
TBH, delete p = nullptr; reads too much like delete (p = nullptr);, even if
it doesn't parse that way, that I wouldn't ever want to use it, or attempt
reading code that uses it.
