Here is a (hopefully complete) list of all TG classes with shortcuts. Put your name behind it, when you start working on it. that way we can keep track of who does what. Don't forget to update the tests ;P

• CallbackQuery (@Bibo-Joshi )
• Chat (@Poolitzer)
• Message (@Bibo-Joshi )
• Poll (doesn't have one yet, but we should add one for stop_poll, while at it actually that's BS, as Poll has acces to neither chat_id nor message_id, which are needed to stop it.)
• User (@Bibo-Joshi )
• InlineQuery (@Bibo-Joshi )
• All the media types (Animation, Audio, ChatPhoto, Document, PhotoSize, Sticker, VideoNote, Video, Voice) @Bibo-Joshi
• Passportfile (@Bibo-Joshi )
• Precheckoutquery (@Bibo-Joshi )
• Shippingquery (@Bibo-Joshi )
