thanks, Adam
I'd also like to ask about similar code.
If I'm writing code like so, I'm getting error.
What I wanted to, is `this` to be the instance of C2. how can I 
do this?
the second snippet is how I worked it around (explicitly defined 
and used template type  parameter), but is there better solution?
```D
import std.stdio;

class C1
{
     void writetext()
     {
         this.writetext_x();
     }

     void writetext_x(this T)()
     {
         const id = __traits(identifier, T);
         pragma(msg, "generating writetext for ", id);
         static assert(is(T == typeof(this)));
     }
}

class C2 : C1
{

}

void main()
{
     auto c2 = new C2;
     c2.writetext_x();
}
```

```D
import std.stdio;

class C1
{
     void writetext()
     {
         this.writetext_x();
     }

     void writetext_x(T)(T new_this)
     {
         const id = __traits(identifier, T);
         pragma(msg, "generating writetext for ", id);
     }
}

class C2 : C1
{

}

void main()
{
     auto c2 = new C2;
     c2.writetext_x();
}
```
