I just don't feel that everything that can be abstracted away, should 
be. Sometimes a trivial list is just a ->next, and doesn't need any more 
than that. Sometimes, I just want to do x*x*x rather than abstracting 
away a cube(T)(T x) function.

An abstraction becomes useful when it's repeated repeatedly, not when 
it's used once or twice.
