What is the D equivalent of C++'s method pointers?

[Tejas]

Given a class ```Employee``` , if I have the following code
```
int (Employee::*methodPtr) () const { &Employee::getSalary };
Employee employee { "John", "Doe" };
cout << (employee.*methodPtr)() << endl;

```

What is the equivalent D code?

Ditto for pointer to class instances:

```
int (Employee::*methodPtr) () const { &Employee::getSalary };
Employee* employee { new Employee { "John", "Doe" } };
cout << (employee->*methodPtr)() << endl;

```
