typeof(&method) fails unless method is static. Says & requires
this.
But for typeof, it shouldn't matter and should pass.
So how to get a function pointer to a non static member
function(of an interface)?
I've tried creating the type like
T t;
typeof(&t.method) fptr;
but same issue. It may be because T is an interface, but again,
it shouldn't matter. I just want the function pointer declaration.
e.g., `void function();` for `void foo();`
This is to avoid building the declaration myself which may be
error prone.
