Getting the return value from the underlying method of an Enumerator
This is documented in the example code, but easy to miss.
When you get an Enumerator using #to_enum(:method_name, …), you can get all of the yielded values using #next, but not the value that is finally returned.
That value can be retrieved via the #result attribute of the StopIteration exception object that is raised when calling #next after the underlying method has returned.
