I have written a blog post about operator overloading for structs.

You can find it here: https://www.reddit.com/r/programming/comments/4m8mgr/operator_overloading_for_structs_in_d/

Comments and suggestions are appreciated.

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.

Things usually go better on Reddit if you post as the first comment a summary of what the article is about.

Also, if you post your own articles, Reddit is likely to put you on their auto-ban list :-(

I'll do it in future posts then :)

Announce the post here and ask someone to post it to reddit for you.
