Kotlin Property: "Type parameter of a property must be used in its receiver type"

I have the following simple Kotlin extension functions:

// Get the views of ViewGroup
inline val ViewGroup.views: List<View>
    get() = (0..childCount - 1).map { getChildAt(it) }

// Get the views of ViewGroup of given type
inline fun <reified T : View> ViewGroup.getViewsOfType() : List<T> {
    return this.views.filterIsInstance<T>()
}

This code compiles and works fine. But, I want the function getViewsOfType to be a property, just like the views. Android Studio even suggests it. I let AS do the refactoring and it generates this code:

inline val <reified T : View> ViewGroup.viewsOfType: List<T>
    get() = this.views.filterIsInstance<T>()

But this code doesn't compile. It causes error: "Type parameter of a property must be used in its receiver type"

What is the issue here? Searching for help on this error doesn't seem to lead to an answer.
