No... this doesn't matter. The first print will only allow to test if 
input data are there.

One may also just write

          print;
          print OUT;

when using $_.

And a one-liner version I posted before (its different a bit from the 
original one of William, since file names are define as STDIN and STDOUT 
on command line):

perl -e 'while(<>){ print; }' < input.txt > aoutput.txt
