		ci.enumeration = p_property.class_name;
	}
	ci.type.type_source = GDScriptParser::DataType::ANNOTATED_EXPLICIT;
	ci.type.builtin_type = p_property.type;
	if (p_property.type == Variant::OBJECT) {
		ci.type.kind = GDScriptParser::DataType::NATIVE;
		ci.type.native_type = p_property.class_name == StringName() ? "Object" : p_property.class_name;
	} else {
