Hi Julien,
Don't despair! I have tried to get people to warm up to dict addition too -- in fact it was my counter-proposal at the time when we were considering adding sets to the language. I will look at your proposal, but I have a point of order first: this should be discussed on python-ideas, not on python-dev. I have added python-ideas to the thread and moved python-dev to Bcc, so followups will hopefully all go to python-ideas.

Hello, Sorry to annoy the very busy core devs :) out of the blue
I quite noticed people were 1) wanting to have a new dict for Xmas 2) strongly resenting dict addition. Even though I am not a good developper, I have come to a definition of addition that would follow algebraic rules, and not something of a dutch logic. (it is a jest, not a troll) I propose the following code to validate my point of view regarding the dictionnatry addition as a proof of concept : https://github.com/jul/ADictAddiction/blob/master/test.py It follows all my dusty math books regarding addition + it has the amability to have rules of conservation. I pretty much see a real advantage in this behaviour in functional programming (map/reduce). (see the demonstrate.py), and it has a sense (if dict can be seen has vectors). I have been told to be a troll, but I am pretty serious. Since, I coded with luck, no internet, intuition, and a complete ignorance of the real meaning of the magic methods most of the time, thus the actual implementation of the addition surely needs a complete refactoring. Sheers, Bonne fêtes Julien
