Hi:
What is the alias Min = xxx mean? why need defined a alias Min in Min template?
```
template Min(alias pred, Args...)
if (Args.length > 0 && __traits(isTemplate, pred))
{
    static if (Args.length == 1)
    {
        alias Min = Alias!(Args[0]);
    }
    else static if (isLess!(pred, Args[1], Args[0]))
    {
        alias Min = Min!(pred, Args[1], Args[2 .. $]);
    }
    else
    {
        alias Min = Min!(pred, Args[0], Args[2 .. $]);
    }
}

```

I can't explain in detail, but I know, this is called an eponymous template.
