2.054 beta regression.

struct Double1 {
    double val = 1;
    alias val this;
}

struct DNAHash(T) {
    T[] data;

    this(ubyte width) {}

    ref T opIndex(S)(S seq) {
        return data[0];
    }
}

void main() {
    auto hash = DNAHash!(Double1)(2);
    hash["f"]++;
}

test9.d(18): Error: var has no effect in expression (__pitmp5)
