It's common that you'll see the following two lines in C++ code:

delete p;
p = nullptr;

How about allowing it as follows?

delete p = nulltpr;

This is already trivial:

template<class T>
void erase(T*& p)
{
    delete std::exchange(p, nullptr);

}

int main()
{
    auto p = new foo;
    assert(p);
    erase(p);
    assert(!p);

}
