Hi Julien,<br><br>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.<br>

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