I'm very new at this, but I look at using yield wherever in C I would
have used a function pointer.

As an example, c's qsort().  You pass in the comparitor method there
(Java uses an interface for this).  In ruby, your sort could take a
block instead.  

("sort" may not be a great example, as it's built in a number of
useful places...)
