644ecb5190Both `ArrayFormatter` and `StringFormatter` accept an instance of the `Translator`. Thinking about it a bit better, I realised that a formatter might not always need a `Translator`, but it will surely need a `Renderer`. Besides, the `InterpolationRenderer` needs to take translation into account, so it seems more natural to me that this is the one that will get an instance of the `Translator`, as other implementations of the `Renderer` might not even deal with translations.
