The follow code works in Kotlin 1.2.71 but gets error in 1.3.0-rc-190 (Unsupported [suspend operator “getValue”]), will this feature present in 1.3?

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

It is pretty useful for async lazy.

No, they’ve been forbidden in 1.3 since they are not fully supported at the moment (KT-24866)

I’m sorry, it is a pretty feature.
Should I open a new issue about it? I wish to put my vote on it.

Thank you for noticing, looks like there wasn’t any relevant issue.
I’ve created one: https://youtrack.jetbrains.com/issue/KT-27871
