I'm currently updating some of my code to take advantage of C++0x features where available, but I also want to retain backwards compatibility with C++03. I was looking at scoped enums and noticed a thread on the mailing list by Beman Dawes discussing a scoped enum emulation implementation for Boost. I see that it's currently being used by Boost, and resides in /boost/detail/scoped_enum_emulation.hpp. My question is, why is this an implementation detail? Would it be possible for it to be moved to Boost.Config with the other 'helper' macros like BOOST_CONSTEXPR? Obviously it's not hard to reimplement, but I figured that it would be useful to other library users, so it would be best (imo) if it were moved somewhere public, rather than being hidden away. Thanks.
