[wp-testers] Codes within posts breaking themes...

[Idled Soul]

I'm not sure if this was mentioned before or not, but when adding codes 
to posts, it breaks the Default theme or any theme really.

<code>
<div class="entry-content">
                    <?php the_content(''.__('read more &raquo;').''); ?>

                    <?php link_pages("\t\t\t\t\t<div 
class='page-link'>".__('Pages: '), "</div>\n", 'number'); ?>
                </div></code>

I know there is plugins out there for stuff like this, but any chance 
WordPress will allow this function to be prepackaged in WordPress 
themes, and itself? Or is it there, and I'm just not adding the code 
right? :P This is on 2.7 and the regular mode for editor...
