// FactoryFixed is a helper that creates a Factory that just returns some given
// single provider.
//
// Unlike usual factories, the exact same instance is returned for each call
// to the factory and so this must be used in only specialized situations where
// the caller can take care to either not mutate the given provider at all
// or to mutate it in ways that will not cause unexpected behavior for others
// holding the same reference.
