Nice article and effective demonstration of the FunctionalPlus library.
That said, this makes me a bit nervous about shoe-horning functional programming into contexts where it is inappropriate. FunctionalPlus aside, C++ is very clearly designed for an object oriented style (even the name, C++, refers to "C plus objects").
Going too far down the path of working against the intent of the standards committee seems like a recipe for trouble (unless you're just talking about hobby projects).
