Below is a snippet in Devel::Peek documents: 


            use Devel::Peek;
            $a = 42; $a = "hello";
            Dump $a;

    The output:

            SV = PVIV(0xbc288) at 0xbe9a8
              REFCNT = 1
              FLAGS = (POK,pPOK)
              IV = 42
              PV = 0xb2048 "hello"\0
              CUR = 5
              LEN = 8

I found XOK(X would be P, I, N etc.) always follow a pXOK. I looked up perldoc, say XOK means public data, pXOK means private data. But what does it really mean? Please enlighten me, Thanks
