Just an private `alias`,where is break?

`version std0=std2021`,is so easy.

`std.v2_0_1`,too ugly.This is not the right way.

User only need change `std` to `std0`,and every new feature is Ok 
for use.If he want `stable` release,He does nothing.`std` is 
already there .
`Just` maintainer merge `std0` into `std`.
