I'm not sure if you understand the important difference though --it's
not just a differnce in coding, but in actuall functionality. Your
approach has a side effect you might not have considered. You see
you're evaluating the code directly into the base class/module. In
effect you copy the methods rather than include/extend. What happens is
that if you were to define the same method in your class, you would
over-write it completely. You could not use #super to "call-up" to the
module version. In other words your approach might seem less complicate
and thus more elegant, but it actually thwarts the use of
"inheritance".
