Interesting. I guess the conversion to member pointer also works for member function pointers on compliant compilers. I notice that the following program doesn't compile with gcc 3.4 though:
struct nullptr_t { template<typename T> operator T*() const { return 0; }
template<typename T, typename U> operator T U::*() const { return 0; } };
const nullptr_t nullptr = {};
struct A {};
int main() { A *p1 = nullptr; void (*p2)() = nullptr; int (A::*p3) = nullptr; int (A::*p4)() = nullptr; }
I'm surprised too. I always though that T U::* and T (U::*)() are very different types. I didn't find in the Standard any notes that they are the same. -- Best regards, Andrey mailto:andysem@mail.ru
