`std0` is similar to the `C++latest` switch, and `std` is the 
stable version.
We didn't do anything, we got the `stable/latest` version. 
`Win-win`.
You need `stable version`,Ok use `std`. You need `latest 
version`,ok use `std0`.
It also takes `3` months to enter the stable version. At the same 
time, it is synchronized with the release of `DMD`.
Why? Because many people want to use the latest features at the 
first time.
Users of the stable version also hope to get the latest version 
without modification.
Large and full use, but also easier to expose `bugs`.
