IIRC, you're not allowed to use names like _B (one underscore followed by a capital) or names like __b (two underscores). I think names like _b are OK. If they're not, we're un trouble becuase Boost.Bind, Boost.Lambda and Boost.MPL use _1 as a placeholder.

_b is only reserved in the global namespace.
