never tought to use -MO=Deparse to inspect a oneliner! this trick push me even more up in the dark oneliner side of the source..

Anyway -p seems to superseed -n in both order, results are equal:

perl -MO=Deparse -p -n -e 1
LINE: while (defined($_ = <ARGV>)) {
    '???';
}
continue {
    die "-p destination: $!\n" unless print $_;
}
-e syntax OK

perl -MO=Deparse -n -p -e 1
LINE: while (defined($_ = <ARGV>)) {
    '???';
}
continue {
    die "-p destination: $!\n" unless print $_;
}
-e syntax OK'
