Actually, he is justified. It's one thing to work in C or assembly and
write code that depends on certain bit-pattern representations of data
(although even that causes trouble - assuming that
sizeof(int)==sizeof(int*) isn't good for portability), but in a high
level language, you cannot assume any correlation between objects and
bytes. Any code that depends on implementation details is risky.
