Monks, hi there!

I followed a node here while ago and one part of the code got me going, I wish someone could show me a better way to accomplish this issue, I can't figure it out. Is got to be a better and simpler way to do this.
It needs to place a space in the $ref_b to make sure consistency when generating a report out of this and avoid errors.

use strict;
use warnings;
use Data::Dumper;

my $ref_a = [
             [ qw/a b c/ ],
             [ qw/d e f/ ],
             [ qw/g h i/ ],
             [ qw/x y z/ ],
             [ qw/3 4 5/ ],
             [ qw/6 7 9/ ],
            ];

my $ref_b = [
             [ qw/j k l/ ],
             [ qw/m n o/ ],
             [ qw/p q r/ ],
            ];

for my $i (0..$#$ref_a) {
    push @{$ref_a->[$i]}, @{$ref_b->[$i]};
}
print Dumper($ref_a);

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
• Want more info? How to link or How to display code and escape characters are good places to start.
