How to use translated taxonomy in page collections

Hi.

I'm trying to get the pages in collection through their taxonomy filter. I have this code in a twig template:

{% for page in page.evaluate({'@taxonomy.category':'featured'}).order('date', 'desc') %}

I'd like to change 'featured' to a translated string, like this:

{{'THEME_NAME.TAXONOMY_TAGS.FEATURED'|t}}

( THEME_NAME.TAXONOMY_TAGS.FEATURED is a variable configured in languages.yaml translated into two languages. )

I get the following error:

A hash value must be followed by a comma. Unexpected token "name" of value "TAXONOMY_TAGS_FEATURED" ("punctuation" expected with value ",").

Is there anyway to use translated variables in taxonomy filters?

Thanks in advanced.
