How is this different from using a std::map and boost::assign's map_list_of?
Internally it uses an std::map for the runtime lookup, so in that sense maybe not much. But using an std::map won't allow you to do compile-time enum value->string translation. I was also trying to minimize the number of times you had to refer to a single enum value v, so that for example you didn't have to do 2 separate declarations for a compile-time lookup and a runtime lookup. So if you use map_list_of that will give you a runtime lookup and then I think you'll need to respecify all the values using some other mechanism if you additionally want a compile-time lookup. It might be possible to do compile time string->enum translation as well, I know some work was done on an mpl::string, but admittedly I'm still an mpl novice and I didn't look into it.
