Great!

Agreed, but that only surpresses the headers. You still have to read in
the entire PDF at once, and then pass it around as a reference.
You had asked for a way to send the PDF a few pieces at a time to
avoid having the entire file in memory at once. Setting
'$ENV{CGI_APP_RETURN_ONLY}', in combination with passing 'none' into
header_type(), does exactly that :-)
I was just saying that I hope that there might some day be a less cryptic
way of going about that. Perhaps it would work today by returning a hash
from the run_mode, instead of a string. Then, we could have an overloaded
stringify operation call a custom output procedure when CGI::App calls
"print $output" at the end of the run() method. That output procedure
would then read a file in, line by line, and avoid the overhead of
slurping it in during the run_mode. However, some might suggest that
doesn't really make it any less cryptic ;-)
