Why not use the delegate? What exactly do you want to do? Set
after constructor or assign delegate?
```d
struct S {
float /*------------------*/ a;
float /*------------------*/ b;
void delegate(float x, float y) set;
auto sum() { return a + b; }
}
void main() {
S s;
s.set = (x, y) {
s.a = x;
s.b = y;
};
s.set(10, 20);
assert(s.sum == 30);
}
```
