Compiler plugin question:

How do I get the type parameters of an property like List<SomeType> as IrType?
I tried backingField!!.type.originalKotlinType!!.arguments , but I don't know how to get from a TypeProjection to an IrType ...

You can try .type or just cast projection to type

I had to cast first, to get to the arguments . This is the helper I came up with

private val IrProperty.typeArguments: List<IrType>
    get() {
      val asSimpleType = backingField!!.type as IrSimpleType
      return asSimpleType.arguments.map { it.typeOrNull!! }
    }
