Code similar to what Xavier posted is in Boost 1.65+, but if you want to 
support earlier versions of Boost (or use std::optional instead of 
boost::optional), you have to do something like that. It would probably 
be worth adding an overload that works with std::optional, but I don't 
know if I'll have time in the near future to shepherd a patch into Boost.
