Overview

Workaround for nil-valued variables in Liquid templates:

https://github.com/Shopify/liquid/issues/749

This is something that we can pass in to Liquid::Template.render that gets evaluated as nil. If we pass in a nil value directly, then Liquid ignores it and considers the variable to be undefined.
