Hello people, I noticed Context Receivers don’t support star projection and variance annotation, e.g.:
• context(List<*>)
• context(List<out SomeBaseStuff>)
As compilation crashes with

The root cause java.lang.IllegalStateException was thrown at: org.jetbrains.kotlin.psi2ir.generators.DescriptorStorageForContextReceivers.getSyntheticField(DescriptorStorageForContextReceivers.kt)

…

Caused by: java.lang.IllegalStateException: No synthetic field for receiver value …

Is this something expected and we’re just lacking IDE support, or is it something that will be fixed?

It is fixed in 1.8.20. Also, snippet underneath works well on my computer with Kotlin 1.8.20:

fun main() {
    with(listOf(1, 2, 3)) {
        println(test())
    }
}

context(List<*>) fun test() = size

Mh strange, we should be on 1.8.21 🤔 let me check the dependencies!
