You might consider creating your own custom tag. This example is probably not well thought through, it's basically just a tweaking of the example given at the end of perlre, but I'd never tried this before so I did what came easy:)
#! perl -slw
use strict;
package CustomReTag;
use overload;
sub import {
shift;
die "No argument to customre::import allowed" if @_;
overload::constant 'qr' => \&convert;
}
sub invalid { die "/$_[0]/: invalid escape '\\$_[1]'"}
my %rules = (
'\\' => '\\',
'Y|' => qr/<\w\w>/
);
sub convert {
my $re = shift;
$re =~ s{ \\ ( \\ | Y . ) }
{ $rules{$1} or invalid($re,$1) }sgex;
return $re;
}
package main;
my $s = '<5b>I <5c>like <5d>tacos';
my $re = CustomReTag::convert '(\Y|tacos)';
$s =~ s[$re][yummy $1]g;
print $s;
__END__
P:\test>junk
<5b>I <5c>like yummy <5d>tacos

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).

are good places to start.
