Overriding a block within an include

base.html

{% include 'partial.html' %}

partial.html

{% block contents %}
partial.html
{% endblock %}

extension.html

{% extends 'base.html' %}
{% block contents %}
extension.html
{% endblock %}

---

Nunjucks 1.3.4 actual:

partial.html

Expected (?):

extension.html

This reminds me of React’s children or Vue’s slot mechanism, which in turn would suggest a syntax like:

{% include 'component' %}
  {% block main %}
    <!-- block content here -->
  {% endblock %}
{% endinclude %}

which avoids the name collision issue by scoping blocks within the context of the included template. (I don’t know how parser internals work here, though, so no idea how feasible this would be - and at some point, you might just be better off using SSR support in React / Vue to perform static site generation, heh.)

It doesn’t relate to #539, IMO.
