In what namespace and in what header is try_find defined?
Haven't thought about this and here's a guess: #include <boost/try_find.hpp> ... boost::try_find( users, user_id ).map( [](auto& user) { user.status = deactivated; return user; }); In this case `try_find` would return `boost::optional`. And `std::try_find` could return `std::optional`. Thanks
