Re: [Python-ideas] Augmented assignment syntax for objects.

FWIW I always liked Dart's/Ruby's/Crystal's/(Coffee|Moon)Script's/WhateverElse's style: class Cls { Cls(this.a); // IT'S MAGIC } but the Python equivalent is admittedly weirder: def ___init__(self, self.attr): partly because, it'd have to work on pretty much any other variable name, yet

Agreed with Steven, although I do find myself a little more annoyed and bothered by a typical init than him I guess. Even so I didn't think the current proposals went far enough. To tilt the balance farther, to make it easier, let's go all the way! Instead of continuing duplication: >>>

Re: [Python-ideas] Binary arithmetic does not always call subclasses first

Now that I am with a real keyboard and screen and have tried to understand the OP, I can actually write up my thoughts on the matter. There are two aspects to the behavior. Giving preference to the class of the right operand if it is a subclass of the left operand's class is reasonable and

Re: [Python-ideas] Augmented assignment syntax for objects.
