factory TagType.fromJson(Object? json_) {
  final json = json_ is Map
      ? _spec.fields.map((f) => json_[f.label]).toList(growable: false)
      : json_;
  return switch (json) {
    [final kind, final functionType] ||
    (final kind, final functionType) =>
      TagType(
        kind: TagKind.fromJson(kind),
        functionType: FunctionType.fromJson(functionType),
      ),
    _ => throw Exception('Invalid JSON $json_')
  };
}
