Is there any alternative for lazy that includes the receiver? So that I can do val Foo.bar by lazy { this.baz } where this is Foo

Didn’t even know that you could have lazily instantiated extension properties

You can even have delegators on plain `val`s in a function body.

To answer your question:
No, there isn’t.
You can write your own Delegator:

class MyLazyDelegate<T>  {
    // For class properties
    operator fun getValue(receiver: Any, property: KProperty<*>): T {
        TODO()
    }
    
    // For stack-frame/heap vals.
    operator fun getValue(receiver: Nothing?, property: KProperty<*>): T {
        TODO()
    }
}

Note that it's a single delegate instance per extension property, so that if you want to store some value for each Foo object being extended, you're gonna need some external storage for that.
