I'm messing around with the new context receivers and I'm seeing what appears to be an issue, but I figured I'd ask here to make sure I'm not just doing something wrong.
(see thread)

[Ruckus]

If I have

operator fun <T> T.invoke(action: context(T) () -> Unit) {
    action(this)
}

This works:

val action: context(String) () -> Unit = {
    length
}
"Test"(action)

but inlining action does not:

"Test" {
    length  // Unresolved reference: length
}

(The actual use case is of course a bit more complex, but that demonstrates the root issue.)

I wasn't sure how to title it

This looks to be the same issue as KT-51243
I explained a workaround here, but TL;DR: rewrite it to be this:

sealed interface TypeWrapper<out A> {
    object IMPL: TypeWrapper<Nothing>
}
operator fun <T> T.invoke(action: context(T) (TypeWrapper<T>) -> Unit) {
    action(this, TypeWrapper.IMPL)
}
