When bad_casting to pointer type, 
dynamic_cast<>() returns NULL.

Is there a standard on good_casting,
I mean is it normal if dynamic_cast changes pointer,
and could dynamic_cast<>() be implemented w/o changing
the pointer if the cast was not bad ?

Thanks in advance,

Potapov Dmitry, dima@florin.msk.su
