The plus operation on two dictionaries feels far more natural as a vectorised merge, were it to mean anything. E.g., I'd expect
{'a': 5, 'b': 4} + {'a': 3, 'b': 1} {'a': 8, 'b': 5} That's only a natural expectation if you also expect the values in your dict to be addable (in the sense of doing something useful with a "+" operator). It never occurs to me to make that assumption because a fair amount of the time it isn't true in my code.
I'm not arguing that we SHOULD make '+' mean recursive addition. I'm just saying that if I never read this discussion, then later read `dict1 + dict2` in code, that's what I'd expect.
And I'm just explaining why that's not what I expect. My code at the moment looks more like lookup_dict[remote_id] = RemoteObject(stuff) so the idea of adding dict values simply doesn't come to me. -- Rhodri James *-* Kynesim Ltd
