template <typename base> struct safe_enum : base;
Actually, now it's class Boolean : public enum_base<Boolean>. If this is still the case, then why shouldn't this
template <typename base> istream& operator>>(istream &, safe_enum<base> &) { ... }
work?
Yeah, I guess I was worried for no reason. operator >> is now implemented much like you suggest. Any plans to request a review? I am unfamilar with the process, where can I get more information about it? I think that the library is almost ready; the bitfield implementation needs to be finished (all bitwise operators should be implemented). I'd really like to try it in a few real-world applications to make sure it is really usable. Latest rev is 4.2 in the file-vault. -Frank
