What kind of feature are you missing? Where do you notice a shortcoming of PTB?

Have a dict representation of TelegramObject without having the attributes also converted to dicts

Describe the solution you'd like

Make TO.to_dict accept a parameter recursion that specifies up to which level attributes should be converted to dict. Logic:

• recursion=None (default) recurs infinitely
• 0 gives a dict representation but doesn't convert attributes to dicts
• 1 converts attributes, but not attributes of attributes
• etc

Describe alternatives you've considered

Alternatively, a simple recursion=True/False could be a step in the same direction with, having the same effect as None/0 described above

Additional context

Would e.g. allow to do ptbcontrib.send_by_kwargs(bot, chat_id=chat_id, **message.to_dict(recursion=0). See also python-telegram-bot/ptbcontrib#39 which was implemented only partly

Just a wild idea so far and of no major importance to me :)
