OpIndex/OpIndexAssign strange order of execution

[Ali Çehreli]

Have you considered the multiple indexes?

   https://dlang.org/spec/operatoroverloading.html#index_assignment_operator

It may give you some power in execution order.

import std.stdio;

struct S {
     auto opIndex(string index) {
         writeln(index);
         return 42;
     }

     auto opIndexAssign(int value, string[] indexes...) {
         writeln(indexes);
     }
}

void main() {
     auto s = S();
     s["b", "c"] = s["a"];
}

Prints

a
["b", "c"]
