This code succeeds to compile with -o- switch.
It means that front-end allows such a meaningless expression, (int[]).length.

void main()
    foreach (A; TypeTuple!(int[1], char[1], int[], char[]))
        auto len  = A.length;
        auto rev  = A.reverse;
        auto sort = A.sort;
        auto dup  = A.dup;
        auto idup = A.idup;

Of course, the invalid expressions will fail code generation in glue layer, but it is little late.
