A modern programming language that makes developers happier.

kotlinlang

is there a way to create a `Delegates.observable` of a read-only property? e.g.

```
data class Foo(bar:Boolean, car:Boolean)
val foo by Delegates.observable(Foo(false,false)){...}
foo.bar = true
 ```

Observable field cannot detect such changes and notify.
```foo.bar = true```

To do that bar must be Delegates.observable itself

hmm :confused: ty, I just found out from the docs

Maybe you could make the setter private though? 

&gt; make the setter private though
But sample code itself is impossible, you cannot observe changes of nested property (foo.bar), you can observe changes of foo itself
