Are there a couple of examples showing real-life C++ problems that can be solved with the help of FC++?

The paper FC++: Functional Tools for OO Tasks on the FC++ web page talks about how to use FC++ in the implementation of common OO design patterns. The web page also points to the XR

and for all these patterns we already have different (much better IMO) solutions.

help, within a normal C++ program. The quicksort example was very cool, but it turns out that the generated code is too slow to be used for everything. If I need FP everywhere, I change language. The quicksort example and also the tree iterator example I posted are interesting. I posit that there are cases where shorter/easier code may be more valuable than code that wins on raw performance, but perhaps this is too-unpopular an idea among C++ people.

Do you really beleave that quicksort could be an example that shows usefullness of lazy lists? I don't say that raw performance sould be primary goal, but an abstraction price should be commensurable to advantages. And I still do not see a single example of that. Gennadiy.
