Yes, the dict is more pythonic. I thought about it, I went for the tuples it was 
simpler to implement (and use in my use case). But giving a second thought it 
makes more sense to do a dict.

I didn't thought about that, but you are right, with prop="" you get the full 
list of properties of the message. Nice, let's put it as default value.
