This doesn't work, I have shown the given error messages in the original post:
//#3
struct Vec {
Vec opOpAssign(string Op)(auto ref Vec other) if (Op == "+=") {
return this;
}
Vec opBinary(string Op:"+")(Vec other) {
Vec result;
return result += other;
}
}
void main() {
Vec v;
v += Vec() + Vec(); // line 13
}
It works if you remove "auto ref". I think this is a compiler bug. I will put
it in bugzilla. The program #1 and 2# are instead correct according to D specs.
