I use this code to get member function address on runtime:
=========
struct A {
this(){};
}
auto ctor = (&__traits(getMember, A.init,"__ctor")).funcptr;
=========
my question is, how to get it in compile time like static
function address:
=========
struct A {
void d(){};
static void fn(){};
}
enum FN = &A.fn; // static method address is ok
enum A0 = &(A.d).funcptr; // Error: need this for d of type void()
enum A1 = (&__traits(getMember, A,"d")).funcptr; // Error: no
property funcptr for type void function()
enum A2 = (&__traits(getMember, A.init,"d")).funcptr; // Error:
(&A().d).funcptr cannot be evaluated at compile time
=========
