Optional was implemented to be safe and slow because it was targeting safe and slow use cases. For POD types and anything that has a default constructor a std::pair<bool, T> seems fine to me.
I'm failing to see why optional should be slow. I use it extensively, POD types included, and I don't consider pair<bool, T> as a valid replacement. I'll be glad if it gets optimized for POD types, why not?
