For example:
use 5.010;
use strict;
use warnings;
BEGIN {
# Allow false to be modified.
&Internals::SvREADONLY(\!!0, 0);
# Modify false to be equal to 1.
${\!!0} = 1;
# Disallow false to be modified again.
&Internals::SvREADONLY(\!!0, 1);
};
say "left is right!" if "left" eq "right";
say "up is down!" if "up" eq "down";
say "black is white!" if "black" eq "white";
say "maths is flawed!" if 7 > 100;
perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'

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).

or How to display code and escape characters
are good places to start.
