Is it possible to rewrite the following `ViewModel` private extensions function into a public, standalone function which can be used by all ViewModels in a project?

```private fun <E> SendChannel<E>.sendOneTimeEvent(event: E) {
    viewModelScope.launch {
        send(event)
    }
}```
I thought, it might work by leveraging the experimental *context receivers* feature `-Xcontext-receivers`.

```context(ViewModel)
fun <E> SendChannel<E>.sendOneTimeEvent(event: E) {
    viewModelScope.launch {
        send(event)
    }
}```
But this raises an error at call site:

> No required context receiver found: Cxt { context(androidx.lifecycle.ViewModel) public fun <E> kotlinx.coroutines.channels.SendChannel<E>.sendOneTimeEvent(event: E)

Something about doing a `launch` just for a `send` seems incorrect to me. Why not just have an unbounded channel and use `trySend`?

Then you wouldn't even need the `viewModelScope`.
