Version 2.026, not sure why that's not an option yet in the version list.
struct Const {
uint[2] num;
ref uint opIndex(uint index) const {
return num[index];
}
}
Error message by compiler:
Error: cast(uint)(this.num[index]) is not an lvalue
This may be technically correct if the compiler is trying to cast away const to return the reference, but the error message should really be related to the fact that you can't return a non-const reference here without violating const correctness.
