我花了过去两周的时间制作这个玩具编程语言。<p>我基本上是复制了 Go 的扫描器/解析器，并将语法修改为函数返回单个值。这使得可以正确使用 Result/Option 类型，并通过运算符传播错误。<p>我还希望能够使用简短的“类型推断”匿名函数，以便能够使用像 Map/Reduce/Filter 这样的函数，而不必使用 100 个字符来指定类型。
Many iPhone users have shared Tweets reporting that they got an unsolicited "notification ad" from Apple Pay (Wallet app) (e.g. https://x.com/jbillinson/status/1937508135343649189 ). Apparently, the Wallet app in ios 26 (beta) has an option to "turn off" such ads (by toggling the "Offers & Promotions" in Wallet Notification).
Since Google Glass made its debut in 2012, there's been a fair amount of hype around augmented reality and related tech coming into its own in industry, presumably enhancing worker productivity and capabilities.<p>But I've heard and seen so little use in any industries. I would have thought at a minimum that having access to hands-free information retrieval (e.g. blueprints, instructions, notes, etc), video chat and calls for point-of-view sharing, etc would be quite useful for a number of industries. There do seem to be interesting pilot trials involving Hololens in US defense (IVAS) as well as healthcare telemonitoring in Serbia.<p>Do you know of any relevant examples or use cases, or are you a user yourself? What do you think are the hurdles - actual usefulness, display quality, cost, something else?
