SelectSaver - save and restore selected file handle
use SelectSaver;
{
my $saver = new SelectSaver(FILEHANDLE);
# FILEHANDLE is selected
}
# previous handle is selected
{
my $saver = new SelectSaver;
# new handle may be selected, or not
}
# previous handle is selected
When a "SelectSaver" is destroyed, it re-selects the file handle that was selected when it was created.
