In perl you cann't store array as value of hash but reference.

maybe following is what you want.

use strict;
use warnings;

my %headers;

open IN, "<$ARGV[0]";
my @v1 =3D split("\t \n", );
my @v2 =3D split("\t \n", );
$headers{"keys"} =3D \@v1;
$headers{"info"} =3D \@v2;

for my $key (keys %headers){
print "$key =3D> @{$headers{$key}}\n";
}
