I have not personally ever used the walrus operator, and I don't think I've even seen it used in the wild, either.
That's not a commentary on how useful it is, but that it takes time for changes like this (that can't be back-ported) to get much real world use. So no, I don't think it's time to relax the restrictions -- for the same reason the restrictions were there in the first place. - CHB On Sun, May 8, 2022 at 9:40 AM Steven D'Aprano <st...@pearwood.info> wrote: > On Sun, May 08, 2022 at 04:00:47PM +0100, Rob Cliffe wrote: > > > Yes, I know unrestricted use of the walrus can lead to obfuscated code > > (and some of Steven's examples below might be cited as instances 😁). > > They're intended as the simplest, least obfuscatory examples of using > the walrus operator that is not pointless.
