You simply "place" new stuff in that storage. The "previous" 
non-POD stuff doesn't exist anymore (as soon as you've placed 
some other {sub-}object in that storage) as far as C++ is 
concerned. AFAICS, you can have char "copies", but you just 
can't use your bunch of copied chars to "revive" evaporated 
non-POD stuff.
