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;

All I found was this post from 2005(!):
