Woah!
That works. I expected it would fail because the first group would match everything and then there would be nothing for the 2nd group to match against.
Here's the code I used to test:
#! /usr/bin/perl -w -T
use strict;
my $str = 'foo_bar_foo_bar_12345';
print "$str\n";
$str =~ /(.*)(\1.*)/ || die "Failed!\n";
print "$2\n";
Can anyone explaine why that is?

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).
