We are a "magic" set processor.
So we are (I think) supposed to look at "private" flags
and set the public ones if appropriate.
e.g. "chop" sets SvPOKp as a hint but not SvPOK
presumably other operators set other private bits.
Question are successive "magics" called in correct order?
i.e. if we are tracing a tied variable should we call
some magic list or be careful how we insert ourselves in the list?
