I never question usefulness of function object (any-morphic). What I do seek is an example of lazy list application.

Then you should say so. "FP has no advantages" is a far cry from "Lazy lists have no advantages".

I actually "cry" "FC++ has no advantages". Take lazy list out of FC++, what we you be left with? Polymorphic function objects? I was agree from the very beginning it should be incorporated. Maybe though not as part of FC++, but boost::function and boost::functional Gennadiy.
