[theme-reviewers] Question about ob_start and ob_get_clean (Vicky Arulsingam)

[Sayontan Sinha]

There are some specific uses I can think of:

   1. Some functions have no "echo" parameter and always print the output.
   If you wanted to run a filter over the output of such a function, this seems
   like an easy way to do so.
   2. Ad hoc insertions of widgets/widget areas. Let's say you have defined
   a sidebar that you want to be able to insert within your posts. You could do
   this by defining a shortcode, which prints out dynamic_sidebar in an output
   buffer.
