* This isn't an algorithm, so I don't want to evoke std::for_each.

What is it that makes std::for_each an algorithm and BOOST_FOREACH not?

You might consider just answering the first part of that question for yourself: "what is it that makes std::for_each an algorithm?"

It's a finite series of well-defined steps. As is BOOST_FOREACH. In any case, we use underlines in keywords and macros, too. For example, "dynamic_cast" or "BOOST_STATIC_ASSERT". -- Dave Harris, Nottingham, UK.
