Who spot the trick?
use strict;
use warnings;
my @unv;
my $pos;
while (<DATA>){push @unv,$.-1,$.,$.+1 if /XXXXX/;$pos=(tell DATA)-leng
+th $_ unless $pos}
seek DATA,$pos,0;
while (<DATA>) {print unless $.-__LINE__ ~~ @unv}
__DATA__
XXXXX
Aoooo
XXXXX is my name
Boooo
11111
22222
33333
Coooo
XXXXX is what I play
Doooo

# OUTPUT
11111
22222
33333

If you spot the trick please explain it to... me!

UPDATE:
the trick can be avoided with a cleaner solotion assigning to
$.
use strict;
use warnings;
my @unv;
my $pos;
while (<DATA>){push @unv,$.-1,$.,$.+1 if /XXXXX/;$pos=(tell DATA)-leng
+th $_ unless $pos}
seek DATA,$pos,0;
$.=0;
while (<DATA>) {print unless $. ~~ @unv}

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).
