Q. What happens to programmers when they die?
A: MS-Windows programmers are reinstalled. C++ programmers become undefined,
anyone who refers to them will die as well. Java programmers reincarnate
after being garbage collected, unless they are in permgen, in which case
they become zombies. Zimbu programmers leave a stack trace that tells us
exactly where they died and how they got there.
