Hi, ...
I have learned that personally I shall never use boost::function. You probably may want to investigate such a code bloat. Though it is probably the known and expected behavior. And I do agree that CCCC is not quite relevant here. Just for information.

P.S. The traditional full story for AAAA, that includes intermediate calls. Though it is not really full -- I have given up for three more calls inside the boost::function1<int,int>::operator() function.
… 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. Julien
