Access outer member of struct from inner struct

[Andrey]

Hello,
In this example how can I access the members "read" and "q" of 
struct Outer from Inner struct?
> struct Outer
> {
> 	ulong q = 1;
>     Inner inner;
> 
>     void read(ulong value)
>     {
>         q += value;
>     }
> 
>     void run()
>     {
>     	q.writeln;
>         read(5);
>     }
> 
>     struct Inner
>     {
>      	void write(string text)
>         {
>             read(text.length);
>             writeln(q);
>         }
>     }
> }
> 
> void main()
> {
>     Outer ttt;
>     ttt.run();
> }

During compilation I get:
> onlineapp.d(55): Error: this for read needs to be type Outer 
> not type Inner
> onlineapp.d(56): Error: need this for q of type ulong
