DESCRIPTION
A SelectSaver object contains a reference to the file handle that was selected when it was created. If its new method gets an extra parameter, then that parameter is selected; otherwise, the selected file handle remains unchanged.
When a SelectSaver is destroyed, it re-selects the file handle that was selected when it was created.
