The pull request of the day: 3998
Hello everybody, All D contributors are invited to have a look at this pull request. It is fairly important for the D language, as it implements the multiple alias this. The pull request number: 333998 https://github.com/D-Programming-Language/dmd/pull/3998 Please focus attention on it today (well, the next 24 hours, it depends when your day starts). Let's bring'it to a state of: to be merged or to be rejected. Many thanks.

I've been waiting for multiple alias this for a looong time, ever since I read about it in TDPL. T -- People tell me that I'm paranoid, but they're just out to get me.

What are some common uses for multiple aliasing? I understand the feature, but curious where it would be commonly employed. To me, this allows structs to have something like inheritance. You add a property for another struct that acts like an interface and alias that struct to the current one. Thoughts?

Multiple inheritance of implementation for structs + implicit casting in one basket I wish that's what we used it for. More often than not, it's used to simulate implicit casting, sometimes with catastrophic results in generic code...
