I guess the cost of boost::function (or std::function) is more than
justified for its use. It is not intended to be used everywhere,
(templates would be prefered where performance matters) but is the
only way to abstract what a function is and abstract its type.

Unless, you have a better way to achieve the effect, I feel your
criticism is rather unfair.
