The get method returns an array *reference*, not an actual array. So your statement should be 
    $msgs[$command]{message} = $pop->get($command);

That will store the array reference in 
    $msgs[$command]{message}

To dump our your @msgs array--to get a sense of what it looks like, visually--you can use Data::Dumper, as jlp suggested: 
    print Dumper \@msgs;
