I think it's conventional to put an underscore before your object variable names too, eg _beverage.
Erm, that's only for private properties, the rest are not prefixed with an underbar.
From perltoot:
Occasionally you'll see method names beginning or ending
with an underscore or two. This marking is a convention
indicating that the methods are private to that class
alone and sometimes to its closest acquaintances, its
immediate subclasses. But this distinction is not
enforced by Perl itself. It's up to the programmer to
behave.
I feel your statement is misleading. New developers could use underbar incorrectly in their own code, and using other folks modules.

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).
