Metaprogramming?  This isn't template metaprogramming if that's what you
mean.

What's the other complexity?

I'm talking about mapped iterator + select1st.

Right.  It's just functional programming (mostly).  Isn't this why
mapped_iterator exists?

In any event, if you really object, I guess I will write separate loops.
Seems like we're throwing away a lot of the power of C++, though.
