I would assume that "thinking like the author" in the case of
SubRequest is that one might serve a page which contains, for
instance, 3 divs which can later be dynamically updated via AJAX
calls, which are in turn also served by Catalyst.  So the first time
around, you can use $c->subreq() to grab the output of those AJAX
calls and stuff them into your template for the whole page and serve
it.  Then later javascript code within the page might call back to
those subreq()'d methods directly to update the individual divs,
without any code duplication anywhere.
