( #3333=superdoc: print w/ replies, xml ) Need Help??
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.
