Yes, I'm interested.

Here is my wish list:

1. only the meta information that is really used should end up in the executable
   (can be done via template instantiations)

2. use a more intuitive name than "smart enum" 
   something like "reflective enum" or so

3. the implementation should store the values in a structure like that

    struct enum_name
    { 
       enum type { [... values ...] };
    private:
       // [...friend declaration & accessors for meta information...]
    };

3.1. the storage type should be a real enum
3.2. its name should be "type" so the enclosing structure can act as a metafunction 
3.3. no public members, access is implemented via freestanding functions
