Is T.init allowed?

[Andrey Zherikov via Digitalmars-d-learn]

Seems compiler allows custom nested type with `init` name:
```d
struct T
{
    struct init {}

    int b = 2;
}

void main()
{
    T t;
    writeln(t);        // T(2)
    //writeln(T.init); // Error: cannot pass type `init` as a 
function argument
}
```

Is it a compiler issue so this shouldn't be allowed?
If this is OK then how can I refer to an initial value of `T` 
(`T.init` doesn't work)?
