local custom getter? (inside a function)

[Derek Peirce]

Example?

[Marc Knaup]

You kinda can already using delegation:

interface Delegation<Value> {
	operator fun getValue(thisRef: Any?, property: KProperty<*>): Value
}

fun <Value> delegation(block: () -> Value) = object : Delegation<Value> {

	override fun getValue(thisRef: Any?, property: KProperty<*>) = block()
}


fun main() {
	val foo by delegation { 42 }

	println(foo) // 42
}

If that’s what you mean 😄

[Marc Knaup]

If you mean val SomeClass.foo get() = 42 then that indeed won’t work.

fun foo() {
   val a get() = 2
}
