Define this use of "dramatically" in a more quantitative and objective
way,
please. Is Java "dramatically" slower than C++/D here?
You can try it for yourself. Take some OOP code of yours, and insert a
null check in front of every dereference of the class handle.
Why would you want to check every time ? You program will get a signal
from the system if it try to deference a null pointer, so thing can be
done in the signal handler, and no cost is involved.
