/**
 * Use this view helper at the first level inside the Field view helper. It will
 * be added to the arguments list, which can then be used inside the field
 * template.
 *
 * It does not add any feature, but allows the Fluid template to be far more
 * readable, as you can see below:
 *
 * Without the Option view helper:
 *
 * ```
 *  <fz:field layout="..."
 *               arguments="{label: '{f:translate(key: \'my_lll_key\')}', foo: 'bar'}">
 *
 *      ...
 *  </fz:field>
 * ```
 *
 * With it:
 *
 * ```
 *  <fz:field layout="...">
 *      <fz:option name="label" value="{f:translate(key: 'my_lll_key')}" />
 *      <fz:option name="foo" value="bar" />
 *
 *      ...
 *  </fz:field>
 * ```

$this->renderingContext of type object<TYPO3Fluid\Fluid\Core\Rendering\RenderingContextInterface> is not a sub-type of object<TYPO3\CMS\Fluid\Core\Rendering\RenderingContextInterface>. It seems like you assume a child interface of the interface TYPO3Fluid\Fluid\Core\Rendering\RenderingContextInterface to be always present.
