- safe bool or explicit bool conversion operator I don't think this is a good idea. Why not? This seems to be not intuitive and not so safe.
It is quite intuitive to me. true means non-null, and false means null.
Would it mean !empty() or !!begin()?
The std::string has no such operator.
Why does that matter? It's still convenient. It would be a nice addition to std::string.
std::string does not have a 'null' state. -- Yakov
