POSIX says that the use of NUL bytes gives undefined behavior in a shell. zsh supports this, but it would take a radical change to bash to support it, with minimal benefit (since you cannot pass such variables on to child processes - after all, the environ variable consists of NUL-terminated entries). > 3.

It's much faster than the alternative of "=". -- Eric Blake
