Hi Joel,
It looks interesting. I've only read the Starter Kit page so far. You went 
from this (without using the library):
    find_if(c.begin(), c.end(), &is_odd)

To:
    find_if(c.begin(), c.end(), is_odd(arg1));

But your functor is a lot longer, and the advantage wasn't explained (or 
perhaps what I mean is that the advantage of lazy evaluation wasn't 
explained or demonstrated here).

Is it any quicker to run? If the advantage is that you get better re-use, 
then I think you need a follow-on example that shows that re-use, and how 
that wouldn't be achieved with normal c++ functors.
