This was a proposed library implementation of nullptr for c++0x from http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2004/n1601.pdf Hmm, it seems it doesn't convert to function or member function pointers...
On what modern compiler does it not?
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; } -- Eric Niebler Boost Consulting www.boost-consulting.com The Astoria Seminar ==> http://www.astoriaseminar.com
