Scope assigned to variable detected as unused

[azrosen92]

We have some translation code that uses one variable across many translations keys. It looks something like

    scope = [:simple_form, :wrong_answers, :style_guide]
    r = Records::StyleGuide.new(
      question_1: t(:question_1, scope: scope),
      question_2: t(:question_2, scope: scope),
    )

i18n-tasks detects this as an unused translation. However when I directly use the scope value in the t() call, i18n-tasks detects it correctly.

    r = Records::StyleGuide.new(
      question_1: t(:question_1, scope: [:simple_form, :wrong_answers, :style_guide]),
      question_2: t(:question_2, scope: [:simple_form, :wrong_answers, :style_guide]),
    )

Is there an existing custom scanner that would cover cases like this? Or any suggestions on how to build one?
