Code convention/"hint" to reduce excessive Feature Envy

Just brain dumping here but how about if reek saw this:

class FarmYard
  attr_reader :cow, :duck, :pig
  
  def ==(other_farm_yard)
    cow == other_farm_yard.cow &&
      duck == other_farm_yard.duck
  end

  def foot_and_mouth(thing)
    cow.feed_to(thing.pig)
    duck.feed_to(thing.pig)
  end
end

it ignored the feature envy in #== because it could see the class name inflected in the parameter other_farm_yard but not in thing.

Not sure this is a good idea - conventions can be opaque - but this is a fairly common case.

WDYT?
