=over =item ARGV The special filehandle that iterates over command-line filenames in C<@ARGV>. Usually written as the null filehandle in the angle operator C<< <> >>. Note that currently C only has its magical effect within the C<< <> >> operator; elsewhere it is just a plain filehandle corresponding to the last file opened by C<< <> >>. In particular, passing C<\*ARGV> as a parameter to a function that expects a filehandle may not cause your function to automatically read the contents of all the files in C<@ARGV>. =back
