Hi,

What's the meaning of the dot in the call to writeln() below?

```d
    .writeln("Hello there!");
```

I haven't found this in the spec or anywhere else. This is used very often in the source code for Phobos.

Thanks,

It is either means "use global scope writeln" in cases when there is local writeln in the scope shadowing global one, or simply a chained calls like myarray.filter().sort().map() each on new line.

Thanks.
