Have you tried it?? Here goes

% perl -012 -e 'print ord $/'
% perl -0012 -e 'print ord $/'
[download]

both versions print 10. Watch out though how you cluster your switches, -e has to be last in a cluster or alone!

Watch out for the special cases of

% perl -00   # paragraph mode
% perl -0777 # slurp mode
[download]
