[boost] Adding optional<T&> find like method to associative containers in boost.

Hi everybody, I presume somebody thought of this before but for some reason it never happened, but just in case it was never discussed I wonder if people here believe adding an nicer version of find(with different name obviously) to associative containers in boost would be beneficial? Since boost::optional allows references this would work. I presume naming is what most people will have strong feeling about. I personally prefer ofind/oat since I love short names, Barry suggested different names in his blog https://brevzin.github.io/c++/2023/05/23/map-api/, e.g. try_at. boost::optional did not get all the updates C++23 std::optional got, e.g. transform that make this usage compose nicely, but those could be added to boost::optional.
