Me acabo de enterar que por fin van a hacer algo sobre el problema de punteros nulos en c++

Tomado de

At last, C++ has a keyword that designates a null pointer constant. nullptr replaces the bug-prone NULL macro and the literal 0 that have been used as null pointer substitutes for many years. nullptr is strongly-typed:
void f(int); //#1
void f(char *);//#2
f(0); //which f is called?
f(nullptr) //unambiguous, calls #2
nullptr is applicable to all pointer categories, including function pointers and pointers to members:
const char *pc=str.c_str(); //data pointers
if (pc!=nullptr)
int (A::*pmf)()=nullptr; //pointer to member function
void (*pmf)()=nullptr; //pointer to function
