We worked through this issue in detail, and over a long period of time, on
the C++ committee. The discussion was repeated, abet briefly, in early
boost postings. A short summary:

* Naming conventions are contentious, and although several are widely
used, no one style predominates.

* Given the intent to propose portions of boost for the next revision of
the C++ standard library, boost decided to follow the standard library's

* Once a library settles on a particular convention, a vast majority of
stakeholders want that style to be consistently used.

* There is a strong preference for clear and descriptive names, even if

So please do follow the lowercase/underscore naming convention (with
uppercase macro names).

(Boost guidelines don't currently say anything about names. I'll add
