+Code block caches notice if the value of a variable argument
+to the code block has changed. If this is the case, the cache is
+invalidated and the code block is re-run. In the following example,
+@code{caller} will not be re-run unless the results of @code{random} have
+changed since it was last run.

+@example
+ #+srcname: random
+ #+begin_src R :cache yes
