Associative arrays give compile error

Now Tuples accept the natural syntax too:
writeln(result[0], " ", result[1]);

I suggest code similar to:

enum E_MODE {
    LSB,  //  0
    USB,  //  1
    DSB,  //  2
    CWL,  //  3
    CWU,  //  4
    FMN,  //  5
    AM,   //  6
    DIGU, //  7
    SPEC, //  8
    DIGL, //  9
    SAM,  // 10
    DRM   // 11
}

void main() {
    // associative array for translation
    with (E_MODE) immutable auto a_mode = [
            "LSB":  LSB,
            "USB":  USB,
            "DSB":  DSB,
            "CWL":  CWL,
            "CWU":  CWU,
            "FMN":  FMN,
            "AM":   AM,
            "DIGU": DIGU,
            "SPEC": SPEC,
            "DIGL": DIGL,
            "SAM":  SAM,
            "DRM":  DRM
        ];
}
