At the time being, filters are parsed entirely before any Ruby is
evaluated. That means that there are no variables to pass them at that
point. However, in the future, we'll probably add the ability for them
to be dealt with either then or when the Ruby is evaluated, depending on
whether or not they receive arguments. In that case, your syntax seems
like a good one to use.
