        It certainly is. Pity it's already in there. :-)  The sysopen()
built-in function allows you to open a file with the O_* flags; look at the
sysopen entry in 'man perlfunc' for details. Furthermore, the
object-oriented IO::File interface allows you to say things like:

        $fh = new IO::File "file", O_WRONLY|O_APPEND;  # from the IO::File
docs.

        Or $fh = IO::File->new("file", FLAGS), for that matter, just to
make Chip happy. :-)  Good job with the quick patch... it's frightening to
think how many common utilities probably have this kind of lurking bug.
