<> is not a "tag" in Perl. It is the read-line operator. It reads
one line from the enclosed filehandle, and returns it. An empty <>
operator has additional magic in that it opens the first file from the
command line and begins reading that. Once the first file is
exhausted, the next file is opened, and so on. If there are no files
on the command line, an empty <> reads from STDIN.
