And here's a perfect situation to take advantage of Sub::Lexical's ability to emulate nested subs ...
use Sub::Lexical;
sub find_key_dupes {
my $binary_tree=shift;
my $key=shift;
my @dupes;
my sub get_dupes($) {
my $node=shift;
return unless $node;
if ($node->{key} lt $key) {
get_dupes($node->{right});
} else {
push @dupes,$node if $node->{key} eq $key;
get_dupes($node->{left});
}
}
get_dupes($binary_tree);
return \@dupes;
}
Thanks demerphq, I'll be using this as valid example code in future. <simpsons voice="Mr. Burns">ehhhxcellent</simpsons>.

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.
