{% block meta %}
{{ author_picture }}
{% endblock %}
<aside>
{% block aside %}
{# Set the default location of the meta #}
{% use 'reused_block.twig' %}
{% block aside_meta %}
{{ block('meta') }}
{% endblock %}
{% endblock %}
</aside>
<article>
{% block article %}
{# empty for now #}
{% endblock %}
</article>
{% extends 'parent.twig' %}
{# remove meta from its default location #}
{% block aside_meta '' %}
{% block article %}
{{ block('meta') }}
{% endblock %}
