Dear all
For example, I have a struct
struct point{int x;int y}
point a;
Is there an easy way to access x and y by using a["x"] and
a["y"]
I guess I need to overload [], but can't figure out how.
Someone can help? Thank you very much

import std.stdio;
struct Something
{
int x, y;
float z;
auto opIndex()(string member) {
switch (member) {
case "x": return this.x;
case "y": return this.y;
case "z": return this.z;
default: assert(0);
}
}
}
void main(string[] args)
{
Something s;
writeln(s["x"]);
writeln(s["z"]);
}

I think this approach should work for me.
Thank you Namespace:)
