  // Natural order

  /**
   * Returns a serializable ordering that uses the natural order of the values. The ordering throws
   * a {@link NullPointerException} when passed a null parameter.
   *
   * <p>The type specification is {@code <C extends Comparable>}, instead of the technically correct
   * {@code <C extends Comparable<? super C>>}, to support legacy types from before Java 5.

### Declare a `list` with a type parameter

To declare types that have type parameters (internal types), like `list`, `dict`, `tuple`:

* If you are in a Python version lower than 3.9, import their equivalent version from the `typing` module
* Pass the internal type(s) as "type parameters" using square brackets: `[` and `]`

In Python 3.9 it would be:

```Python

## API Request Parameters

### Version

Z. B.:

* Um einen *Pfad*- oder *Query*-Parameter zu übergeben, fügen Sie ihn der URL selbst hinzu.
* Um einen JSON-Body zu übergeben, übergeben Sie ein Python-Objekt (z. B. ein `dict`) an den Parameter `json`.
* Wenn Sie *Formulardaten* anstelle von JSON senden müssen, verwenden Sie stattdessen den `data`-Parameter.
* Um *Header* zu übergeben, verwenden Sie ein `dict` im `headers`-Parameter.
* Für *Cookies* ein `dict` im `cookies`-Parameter.

This doesn't go inside of each JSON Schema contained in OpenAPI, this goes outside, in the *path operation* directly.

### Using the `openapi_examples` Parameter

You can declare the OpenAPI-specific `examples` in FastAPI with the parameter `openapi_examples` for:

* `Path()`
* `Query()`
* `Header()`
* `Cookie()`
* `Body()`
* `Form()`
* `File()`

func (l *List[T]) Len() int  { … }

<h3 id="Type_parameter_declarations">Type parameter declarations</h3>

<p>
A type parameter list declares the <i>type parameters</i> of a generic function or type declaration.
The type parameter list looks like an ordinary <a href="#Function_types">function parameter list</a>
except that the type parameter names must all be present and the list is enclosed
in square brackets rather than parentheses
