[boost] Interest in bit-wise flags?

Hi Boost! I have developed a type-safe bit-wise flags class for my own personal use and am wondering if it would be of interest for me to submit it as a Boost library. At the moment it is not ready for submission (code is messy) but I am testing the waters so I present an overview below. * Fully ISO standard C++11 (except for an MSVC version which is API-compatible except it doesn't support as many an infinite number of flag names) * They are type-safe, requiring explicit casts to and from integers/booleans * Supports standard bit-wise operations, and always keep values within the possible set of flags * Supports getting the name of a flag and looking up flags by name at run-time (when a flag is actually multiple-flags it gives something like "A|B") * Supports getting an array of all flags at run-time Now the bad things, which may be a deal-breaker: * Because of limitations in C++ the syntax can feel a bit awkward. You have to use a macro to define flag-names (which actually creates a class) then you can pass those flag-names as template arguments to the flags. An example: FLAG_NAME(A); FLAG_NAME(B); FLAG_NAME(C); typedef Flags::WithValues<0x01, 0x02, 0x04> MyFlags; * I also couldn't get around using the ::WithValues nested class * I use a set of macros to make this cleaner (e.g. the above could be FLAGS(A, B, C)) and once defined there is no more ugliness Thanks for consideration!
