SYNOPSIS ^

    my $duplicate = Code::CutNPaste::Duplicate->new(
        left => Code::CutNPaste::Duplicate::Item->new(
            file => $filename_left,
            line => $line_number_left,
            code => $text_of_code_left,
        },
        right => Code::CutNPaste::Duplicate::Item->new(
            file => $filename_right,
            line => $line_number_right,
            code => $text_of_code_right,
        },
        report => $code_to_report.
    );
