Is there a way in kapt to get a hold of the structure of a function literal with receiver?
When I try to extract info from TypeElement or the Kotlin Metadata library by @Eugenio for a function of the shape: A.() -> B it always shows up as Function1<A, B> but I have not found a place or API that denotes the declaration of such function as being the type of a receiver function.

I think there's something like Protobuf.Function.receiverType if I remember correctly 🤔

The issue is that the type does not represent a Function but the type of an argument of a function, so the only thing I have access there to is the me.eugeniomarletti.kotlin.metadata.shadow.metadata.ProtoBuf.Function#getValueParameterList which gives me a me.eugeniomarletti.kotlin.metadata.shadow.metadata.ProtoBuf.ValueParameter#getType

when I query that type I see no useful info to determine the type is referring to a literal receiver function of the shape A.() -> B

[Eugenio]

oh, right, try searching for the kotlin.ExtensionFunctionType annotation in `Protobuf.Type.jvmTypeAnnotation`: it's a marker annotation that denotes function types with a receiver 😉

Awesome, thanks!
