The block function is used to render the contents of a block more than once. It is not to be confused
with the block tag which is used to declare blocks.
The following example will render the contents of the "post" block twice; once where it was declared
and again using the block function:
twig
{% block "post" %} content {% endblock %}
{{ block("post") }}The above example will output the following:
twig
content
content
