boost::convert<std::string>::from(123) return a converter object. Some might
consider that design decision wacky/bad/etc. but it there for a reason to
satisfy other use-cases.
For 'auto' to work one will need to explicitly call value() as follows:
auto str = boost::convert<std::string>::from(123).value();
