Fix it, then Ship it!

    Let's include `functional` for `std::hash` here.

Lines 233-234 (patched)

    I believe we can simplify this since `boost::hash_combine` is already templated on the
type of the second argument and will call the correct hash function automatically,
    
        boost::hash_combine(seed, option.get());
