Perl doesn't always handle \0 in strings properly.

>dir Directory of dir 2006/06/15 05:58p <DIR> . 2006/06/15 05:58p <DIR> .. 0 File(s) 0 bytes 2 Dir(s) 2,322,644,992 bytes free >echo file contents > file >perl -e "open($fh, qq{file\0junk}) or die; print <$fh>;" file contents

Be wary of system calls and library calls.

Update: Some might say this is the OS's fault, but I expect better of Perl. Conversion from SV to char* results in a loss of information, but Perl apparently assumes it's a safe operation. I shouldn't have to know implementation details of a language's builtins.
