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

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!
