Cool. You missed one very significant thing. That is using 
mixins to take advantage of the operator string.

For example, opOpAssign can be done in one step:

ref Rational opOpAssign(string op)(auto ref Rational r)
    if(op == "+" || op == "-" || op == "/" || op == "*")
{
    mixin("auto tmp = this " ~ op ~ " r;");
    _n = tmp.n;
    _d = tmp.d;
    return this;
}

This is the whole reason, BTW, that operator overloads were 
changed from the original D1 style versions.

Some more examples of your Rational type in action would be 
good too.

Thanks for the feedback! I will update the post tomorrow or on 
Saturday.
