Greetings,
Though I would suggest strongly that you consider using a hash, here is something you can do after your pushes to de-dup your data.
Leave out the unless, since that works fine, and run the following after.
my @non_duplicates = do{
#lets use a hash since we want unique values
#and localize it so its a fresh copy
local %_;
#undef the values of this localized hash
#while assigning your values as keys
undef @_{@{$map{$$row[1]}{$$row[2]}}};
#call keys on the hash to get a list of your
#unique values
keys %_;
}
#assign our unique list back to your original structure.
$map{$$row[1]}{$$row[2]} = \@non_duplicates;
Hope that helps

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).
