It ensures that this wrapper method is called when `send()` is - called. - - Therefore, when you register an object with `ensure()`, you can call its - destructor method yourself, you can let it happen for you, or you can do both. - - The destructor will be called with a single argument describing the reason - for the unload; see `when()`. If `object` does not have the expected - destructor method, then an exception is thrown when `ensure()` is called. - -@param object {object} - An object that defines a destructor method. -@param [name] {string} - Optional name of the destructor method.
