This is why Microsoft's Surface line is great. I have the Go and the stand is wonderful. Plus it transforms into a tiny laptop by snapping on the keyboard.

I actually think it is obvious what a dictionary merge should do (overwrite keys on the left with keys on the right), but this is besides the point because it's already been determined for {**d1, **d2} In other words, there ar

If dicts did subclass sets, then sets would be dicts whose values are all None. In other words, your last example would be defined as: >>> s = {'one', 'two'} >>> d = {} >>> d.up

Your exact point that for sets, union operator is commutative while for dictionaries it wouldn't be is one of the main objections I foresaw if I ever wrote this up as a PEP. Counterpoint: for numbers, + is commutative but for lists it&

Given Python's success with its insertion-order-retaining "compact dict" implementation[1], I've wondered why more languages aren't adopting that design into their maps/hashtables. [1] https://docs.p

Does any of this work with Firefox on Windows/Linux? It would be nice to have this kind of syncing across all platforms.

Yeah... it's ugly as heck but they're clearly trying to avoid new keywords. I hope the TypeScript folks can convince ECMA to adopt normal keywords like they use: https://www.typescriptlang.org/docs/handbook&#x

It also applies to things such as using strings as dictionary keys. Immutable strings allows you to use them as keys without worrying about them being modified and breaking things. It's why Ruby encourages symbols as hash keys. I don&#

Quick correction, the actual url for Xonsh is http://xon.sh . My understanding is that xonsh.org is an out-of-date unaffiliated mirror that the author of Xonsh doesn't control :(

Are there any plans for a native version of Clojure? I'd rather avoid the JVM if possible, but I suppose the whole ecosystem is dependent on it so that's unlikely?

It wasn't about Pocket itself but that Firefox was rudely using notifications to advertise to me. So I went back to Chrome, which has never done anything like that.
