but also to other types that include Go pointers.

All Go pointers passed to C must point to pinned Go memory. Go pointers
passed as function arguments to C functions have the memory they point to
implicitly pinned for the duration of the call. Go memory reachable from
these function arguments must be pinned as long as the C code has access
to it. Whether Go memory is pinned is a dynamic property of that memory

### `Union` in Python 3.10

In this example we pass `Union[PlaneItem, CarItem]` as the value of the argument `response_model`.

Because we are passing it as a **value to an argument** instead of putting it in a **type annotation**, we have to use `Union` even in Python 3.10.

If it was in a type annotation we could have used the vertical bar, as:

```Python

	switch e.getFunctionName() {
	case aggFnAvg, aggFnSum, aggFnMax, aggFnMin, aggFnCount:
		return e.evalAggregationNode(r, tableAlias)
	default:
		// TODO: traverse arguments and call aggregateRow on
		// them if they could be an ancestor of an
		// aggregation.
	}
	return nil
}

// getAggregate() implementation for each AST node follows. This is

	EnvWebhookClientCert = "MINIO_NOTIFY_WEBHOOK_CLIENT_CERT"
	EnvWebhookClientKey  = "MINIO_NOTIFY_WEBHOOK_CLIENT_KEY"
)

// WebhookArgs - Webhook target arguments.
type WebhookArgs struct {
	Enable     bool            `json:"enable"`
	Endpoint   xnet.URL        `json:"endpoint"`
	AuthToken  string          `json:"authToken"`
	Transport  *http.Transport `json:"-"`

var errInvalidArgument = errors.New("Invalid arguments specified")

// errMethodNotAllowed means that method is not allowed.
var errMethodNotAllowed = errors.New("Method not allowed")

// errSignatureMismatch means signature did not match.

            parser.parseArgument(args);
        } catch (final CmdLineException e) {
            System.err.println(e.getMessage());
            System.err.println("java " + SuggestCreator.class.getCanonicalName() + " [options...] arguments...");
