I've used a related idiom in some of my modules -- namely, having a dispatch or aggregator object that operates on several objects simultaneously.
So rather than:
@parms = ...;
foreach $obj (@objects) {
$obj->duckwalk(@parms);
}
I just say:
$ringmaster->aggregate(@objects)->duckwalk(@parms);
If you wonder why you'd ever want to do that, imagine manipulating an HTML::Element tree that represents a table like so:
# Manipulates multiple table cells
$table->col(7)->attr('bgcolor','#BBFFBB');
So to answer your original question, I like the idiom. I consider it a degenerate case of what I illustrated above.

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).
