I got it working inside an eponymous template. D is pretty cool 
actually. :)

enum OPTION
{
    FALSE = 0.,
    TRUE = 1.
}

class One
{}

class Two
{}

template Top(OPTION option) {
    static if (option == OPTION.TRUE) {
        alias Base = One;

    } else {
        alias Base = Two;
    }

    class Top : Base
    {}
}

void main() {
    auto a = new Top!(OPTION.FALSE);
    auto b = new Top!(OPTION.TRUE);
}
