It isn't a full emulation of C++11's scoped enum feature. That's
probably why it ended up in detail rather than config, although I've
forgotten the detailed rationale, if there ever was any.

What do others think? Should  /boost/detail/scoped_enum_emulation.hpp
functionality be moved to config?

Are there any improvements that would make the emulation better,
without turning something simple into something complex?
