This completely surprised me:

        if (!.doMatch(lhsArr, arrArr))

Don't you mean:

if(!.doMatch(lhsArr, rhsArr))

??

            return false;
    }

    return true;
}

bool doMatch(int[] lhsArr, int[] rhsArr)
{
    return true;
}

void main()
{
    int[] x   = [1, 2];
    int[][] y = [[1, 2], [1, 2]];

    bool b = doMatch(x, y);
}

This will enter an infinite loop because the first doMatch overload
gets recursively called. I don't understand why the second overload
isn't picked up as a match in the call "doMatch(lhsArr, arrArr)".

Because arrArr is an int[][] :)
