If you parse it like that, you know that it's pointless. You know that
you wouldn't bother delete'ing a nullptr.

The following two lines of code make no sense:

    p = nullptr;
    delete p;

Therefore when you see "delete p = nullptr;", irrespective of whether
you're familiar with operator
precedence, you know that it must be setting the pointer to null after
delete'ing it, because nothing
else makes sense.
