If I have something like this:

class Foo {
    var number: Int = 0
}

Is it possible to pass a reference to the number property to another class so that the other class can reassign it?

I believe you can pass a KMutableProperty1 to a function and get an instance of from ::number.

You can also access the setter from it pass it somewhere as a Function.

or you pass a lambda around:

val foo = Foo()
val setter: (Int)->Unit = { newValue -> foo.number = newValue }
class Bar( val setNumber: (Int)->Unit )
val bar = Bar(setter)
