in thread the repetition operator does not repeat "\x00" Why?

Data::Dumper prints it for me (Perl 5.8.8, Solaris):
perl -MData::Dumper -e '$_ = "\x00" x 4; print Dumper $_' | cat -v $VAR1 = '^@^@^@^@';

    You are correct, Data::Dumper prints the '\0' but it is only visible in the output via something like cat -v. Nice trick btw, I didn't know about that. Thank you!
