kotlinlang

Just a generic question

Ok, so when I define my kotlin class as
```
class Stuff(a: String, b: String) {}
```
It means that I’ve got two properties that are accessible in the primary constructor, but not stored as the class properties.

But when I do
```
class Stuff(val a: String, val b: String) {}
```
it creates the respective class properties instead.

And the *data* class modifier adds the respective equals() / hashCode() / toString() / copy() implementations.

Right ?
