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.
