There is a makeshift.
File a.cpp
#include <stdio.h>
const class nullptr_t
{
public:
template<class T> operator T*() const { return 0; }
template<class C, class T> operator T C::*() const { return 0; }
// void (C::*pmf)() = nullptr; // Ok
// if (nullptr == pmf) {} // Ok
template<class C, class T> bool operator == (C (T::*p)()) const
{ return p == 0; }
private:
void operator&() const;
// const int n = 0;
// if (nullptr == n) {} // Error
bool operator == (long) const;
}
nullptr = {};
struct C
{
void func();
};
int main(void)
{
void (C::*pmf)() = nullptr;
if (nullptr == pmf) {printf("Ok\n");}
// If there are sentences - send !!!!!!!!
// if (pmf == nullptr) {printf("Ok\n");} // Error
}
> g++ a.cpp
> ./a.out
