Twig Syntax Error when using examples

[schlagmichdoch]

All examples that use arrays as parameters fail with a Twig Syntax Error as the twig array syntax is wrong:

Failing:

{% do craft.prefetch.register('https://anothersite.com/myFonts.css', 'stylesheet', ['media' => 'print', 'crossorigin' => true]) %}

Working:

{% do craft.prefetch.register('https://anothersite.com/myFonts.css', 'stylesheet', {'media': 'print', 'crossorigin': true}) %}
