def fxn(a, (b, c), d):
pass
Python 3 will still allow
def fxn(a, x, d):
(b, c) = x
pass
//javascript
let [x, y] = [1,2]
#python
[x, y] = [1,2]
(x, y) = (1,2)
function fxn(a, [b, c], d) {
console.log(a, b, c, d);
}Uh, thanks?
I would call it anything but "rightful". Making life harder for introspection tools is hardly a rightful reason for removing a core language feature. The code is what most developers are trying to develop, not the introspection tools.
Well that's one reason yes, and by itself not really a good enough one. But if you read the PEP there are another 4 good reasons that you omitted from your comment, why is that?
Because the other reasons were twice as horrible.
"No loss of abilities"? Uh, you can't do this in lambdas anymore.
"Exception to the rule"? Who cares? It was useful and readable, that's all that matters.
"Uninformative Error Messages"? This has never been a pain point for me. If you don't like it then no one forced you to use it...
"Little Usage"? Well I guess everyone matters but me. Which is fine, but then you shouldn't wonder why it would tick me off.
