Yes thats how it is used at the moment. Simple translation string may be __('here is something') and %hash{'here is something'} = translation in specific language. This works fine. Problem arise if i introduce more complicated translations where I can replace internal words in the translated sentence (like word 'something') where am not aware how many specific words can be replace in the sentence where sentence 'here is something' can be 'here is anything' or 'here is nothing' or 'here is the thing'.
