A property containing it's own name:

object Name {
    operator fun provideDelegate(thisRef: Any?, property: KProperty<*>) = property.name
}

operator fun String.getValue(thisRef: Any?, property: KProperty<*>) = this

val foo by Name

fun main(args: Array<String>) {
    println(foo) //prints "foo"
}

kirillrakhman: It's really useful when developing for Android and creating a wrapper for, for example, a SharedPreferences where I could do
foo = "My data"
and the setValue would do something like:

sharedPreferences.edit()
  .putString(property.name, value)
  .apply()

And a similar thing for the `getValue`:

sharedPreferences.getString(property.name, null)

I agree property.name is very useful

But my snippet is about a property that contains just its name, nothing else
