Users need to be cautious about this: > Although Google is part of the minority of the C++ community that doesn’t use exceptions, we recognize that it is a minority and believe that code is often better when it’s exception-safe. We’ve done our best to make things exception-safe. However, we won’t contort things to support all possible exceptions — if you have a hash functor or operator== that throws, we may just mark it noexcept instead.
