I don't think there's a /compelling/ reason, but here's my thought process:

* This isn't an algorithm, so I don't want to evoke std::for_each.
* It's like a new keyword, and some other languages have "foreach" as a 
keyword.

Anyway, I'm not married to the name, and I'd gladly change it if people 
preferred to type an extra underscore. :-)
