I use this code to get member function address on runtime:

my question is, how to get it in compile time like static function address:
=========
struct A {
void d(){};
static void fn(){};
Note: no semicolons needed here
}
enum FN = &A.fn; // static method address is ok
enum A0 = &(A.d).funcptr; // Error: need this for d of type void()
enum A0 = &A.d;
Note that you can't call it at all, but you can get the function
pointer, and put it into a delegate later by assigning .funcptr.
void main()
{
A a;
void delegate() dg;
dg.ptr = &a;
dg.funcptr = A0;
dg(); // calls a.d()
}
