   * <p>Unlike {@link Integer#parseInt(String)}, this method returns {@code null} instead of
   * throwing an exception if parsing fails. Additionally, this method only accepts ASCII digits,
   * and returns {@code null} if non-ASCII digits are present in the string.
   *
   * <p>Note that strings prefixed with ASCII {@code '+'} are rejected, even though {@link
   * Integer#parseInt(String)} accepts them.

Und die von Uvicorn direkt bereitgestellte Version ohne Pfadpräfix (`http://127.0.0.1:8000/app`) wäre ausschließlich für den Zugriff durch den _Proxy_ (Traefik) bestimmt.

Dies demonstriert, wie der Proxy (Traefik) das Pfadpräfix verwendet und wie der Server (Uvicorn) den `root_path` aus der Option `--root-path` verwendet.

abstract class DefaultExistingThing implements ExistingThing {
    private String otherProperty
    public String getOtherProperty() ...
    public void setOtherProperty(String s) ...

    // NOTE: No direct implementation of getSomeProperty

This is acceptable when the implementation type is public and/or has been extended by something outside gradle/gradle:

```groovy
public interface ExistingThing {

Das können wir besser machen.

Wir deklarieren ein `UserBase`-Modell, das als Basis für unsere anderen Modelle dient. Dann können wir Unterklassen erstellen, die seine Attribute (Typdeklarationen, Validierungen, usw.) erben.

Die ganze Datenkonvertierung, -validierung, -dokumentation, usw. wird immer noch wie gehabt funktionieren.

	var (
		c       = d.cur()
		n       float64
		isFloat bool
	)

	// digits first
	switch {
	case c == '0':
		d.scratch.add(c)
		c = d.next()
	case '1' <= c && c <= '9':
		for ; c >= '0' && c <= '9'; c = d.next() {
			n = 10*n + float64(c-'0')
			d.scratch.add(c)
		}
	}

	// . followed by 1 or more digits
	if c == '.' {
		isFloat = true

Diese Funktionen können mit `async def` oder normalem `def` deklariert werden.

### `startup`-Event

Um eine Funktion hinzuzufügen, die vor dem Start der Anwendung ausgeführt werden soll, deklarieren Sie diese mit dem Event `startup`:
