How to use multiple arguments in an if statement with Liquid

I want to use an if statement in Liquid with multiple conditionals. Something like:

{% if (include.featured == "true" and product.featured == "true") or (include.featured == "false" and product.featured == "false") %}

Multiple conditionals don't seem to work. Have I got the syntax wrong or can Liquid not handle this sort of if statement?

Another way you can condense this is to combine else if statements, and booleans don't necessarily need the "==" when evaluating true:

{% if include.featured and product.featured %}
      {% assign test = true %}
{% elsif include.featured == false and product.featured == false %}
      {% assign test = false %}
{% endif %}

Unfortunately, Liquid has a poor implementation of boolean algebra.

Using Liquid's operators and tags, here is a dirty way to achieve it:

{% if include.featured == true and product.featured == true %}
      {% assign test = true %}
{% endif %}

{% if include.featured == false and product.featured == false %}
      {% assign test = true %}
{% endif %}

{% if test %}
      Yepeeee!
{% endif %}
