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?
Can this be implemented as a free function over the public API of unordered
containers? In other words, this signature:

    template< typename UnorderedMap, typename Key >
    auto try_find( UnorderedMap&& u, Key const& k );

Thanks
