Pretty Print Dumper for Hash of Array

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Respectable Monks,
Actually, This is a continuation of my earlier posting. Now with this code,

perl -MData::Dumper -e '
$Data::Dumper::Indent = 0; 
$hoa = {a => [1,2],  'b'=>[1,3], c=> [2,0]}; 
print Dumper $hoa; print "\n";'
[download]

How can I modify it to create:

$VAR1 = {
        'c' => [2,0],
        'a' => [1,2],
        'b' => [1,3]
       };
[download]

Basically my intention is to make the indentation=0 only apply for the array. Thanks.
