Nope, the classes are pure-RAII.  The classes either save or do an "atomic"
save-and-change in the constructor and restore in the destructor.  There are
no member functions you could even use for arbitrarily-timed restoring.  If
you could abuse the RAII paradigm to do this, then....

BTW, why would you need to do this unusual kind of multiple restoring in the
first place?
