Does SAM conversion for fun interface with @Composable works or still WIP? I encountered this:

fun interface SomeComposable {
    @Composable fun Content()
}

val content = SomeComposable { Text("hi") } // <- @Composable invocations can only happen from the context of a @Composable function
val content = SomeComposable @Composable { Text("hi") } // <- type mismatch: inferred @Composable () -> Unit but () -> Unit is expected

It seems it should work, maybe I'm doing wrong or outdated version(I'm using 1.0.1):

only from curiosity what is the benefit using fun interface and no typealias?

[Javier]

With typealias you can pass whatever type which is the same than that typealias. With a fun interface you can only pass that specific type

I know, but if you only hold a composable, personally, I don't see a big advantage

I also think I don't have to do this thing; however, regardless of advantage it should just work.
+ Note that I initially needed this for inheritance.
