[development] development Digest, Vol 96, Issue 22

[Randy Fay]

You don't have to do anything with caching at the render API level. Just
turn on block caching, and it works by default.

Shameless plug about render api resources, though: The render example in
Examples for Developers shows how to do render-api caching and any number of
other cool thinks with the render API. And
http://drupal.org/node/930760gives an introduction to the whole thing.
