is there "this"?

[Konstantin Kutsevalov via Digitalmars-d-learn]

The question is simple.

Is there something like "this" word for classes?

For example:

```
class CLS {

     int numberValue;

     public this(numberValue)
     {
         // how can I put the local numberValue to class property?
         // in some prog language I can do like:
         // this.numberValue = numberValue;
     }

}
```
