This was crossposted while I posted the article on first class functions in
Ruby.
The above problem is exactly what would elegantly be handled by first class
functions. You'd just pass the run function directly instead of having to
create an object that respond to some named function like "run". If more
functions that run were desired, it might be better to create a class, or a
list of functions could be passed in a hashtable.

I think this shows the OOP is great, but there are other concepts that are
also worthwile.
