How to pass a variable into a custom tag in Liquid?

Question

I have written a custom tag in liquid, and I'd like to pass a variable to it. Liquid tags will turn any parameter into a string.

For example:

{% nav page /some/url.html %}

Where page is a variable.

Is there a way to get Liquid to treat page as a variable and not a string?

Thanks in advance!

To answer the general question and not the part specifically about the page variable, you can also pass the contents of the tag through the Liquid parser again:

def initialize(tag_name, markup, tokens)
  @markup = markup
  super
end

def render(context)
  content = Liquid::Template.parse(@markup).render context
end
