Update: This answer isn't really helpful, sorry. Your solutions stores the same references under the sn's, so it should occupy memory comparable to my solution.
If your concern is memory, you can store just the "sn to id" map instead of storing all the data twice.
my %sn_to_id = map { $dat_by_id{$_}{sn} => $_ } keys %dat_by_id;
You then need to nest the references to get the value:
my $sn = 'b';
my $more = $dat_by_id{ $sn_to_id{$sn} }{more};
map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

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).
