[Dancer-users] File extension

Hi all! I have a question about Dancer::Request::Upload. http://search.cpan.org/~xsawyerx/Dancer-1.3095/lib/Dancer/Request/Upload.pm Quote: “ tempname Returns the name of the temporary file the data has been saved to. This will be in e.g. /tmp, and given a random name, with no file extension..” This is my code: post '/upload/:token' => sub { return to_dumper(request->upload('file')); } This is the result: $VAR1 = bless( { 'headers' => { 'Content-Type' => 'image/png', 'Content-Disposition' => 'form-data; name="file"; filename="2.png"' }, 'filename' => '2.png', 'tempname' => '/tmp/QBVx5KfQtB.png', 'size' => '33116' }, 'Dancer::Request::Upload' ); Why does 'tempname' have file extension ?
