[dancer-users] Printing output directly

Hello Dancers, Is it possible to print web page output directly using Dancer2? I'm using Text::CSV_XS to output DB data as CSV like so: while ( my $row = $sth->fetch ) { $csv->print ( $io, $row ); } where $io is a file handle, socket, etc. At the moment, I'm creating a temp file, writing the data, and then using send_file to dispatch the data. Ideally I'd like to just print it straight to the web output, but (e.g.) setting $io to *STDOUT does not work, and there is no serialiser for csv or plain text. Is there a shortcut that I'm missing? Thanks!
