1. pip install django-walrus
2. Add walrus to your settings's INSTALLED_APPS
3. That's it. Now you can go for a swim in ice-cold water, or maybe hunt a penguin.

Once django-walrus is installed, you can use the power of the walrus operator in your template's {% if %} statements:

{% if result := my_mode.some_expensive_method %}
    Wow, check out this result: {{ result }}.
{% else %}
    Nothing to see here.
{% endif %}

As real as a two ton polar mammal.

You can activate some optimizations by setting WALRUS_OPTIMIZED=1 in your shell environment.
