// provider with an input parameter of type ModuleKey. These providers
// may construct a unique value of a dependency for each module and will
// be called at most once per module.
//
// Providers passed to ProvideInModule can also declare an input parameter
// of type ModuleKey to retrieve their module key but these providers will be
// called at most once.
