Have you heard of RSI? People invest hundreds (sometimes thousands) of dollars in ergonomic keyboards just to overcome RSI pain. If you're younger than 30 you might not be impacted by this, but many people who have been typing every day for over a decade are realizing it's not sustainable without proper ergonomics.\n\n> Readability and maintainability are core imo.\n\nI don't think you sacrifice these by having local type inference.

The type of the left-side of an assignment can determine the type (and behavior!) of the right side. For instance, this is ambiguous:\n\n```rust\nlet foo = [(\"a\", 1), (\"b\", 2)].into_iter().collect();\n```\n\nThe expression creates an iterator over the `(letter, number)` pairs, and `collect()` stores the elements in a newly created container. But which container type? Here are two valid variants:\n\n```rust\nlet foo: Vec<_> = [(\"a\", 1), (\"b\", 2)].into_iter().collect();\n```\n\nThis creates a vector with items `(\"a\", 1)` and `(\"b\", 2)`.\n\n```rust\nlet foo: HashMap<_, _> = [(\"a\", 1), (\"b\", 2)].into_iter().collect();\n```\n\nThis creates a mapping where `\"a\"` and `\"b\"` are keys, and `1` and `2` are the corresponding values.\n\nPlayground link in case you'd like to mess with this concept: https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=76f999f4db600415643b0c58c19c69b7","removed":false,"published":"2024-04-08T03:06:57.225950Z","updated":"2024-04-08T03:07:24.801823Z","deleted":false,"ap_id":"https://programming.dev/comment/9036531","local":false,"path":"0.7943069.7946891","distinguished":false,"language_id":0},"creator":{"id":2363616,"name":"BatmanAoD","banned":false,"published":"2023-08-18T03:20:41.788401Z","actor_id":"https://programming.dev/u/BatmanAoD","local":false,"deleted":false,"bot_account":false,"instance_id":79126},"post":{"id":10807520,"name":"Type inference was a mistake","url":"https://borretti.me/article/type-inference-was-a-mistake","creator_id":205319,"community_id":188907,"removed":false,"locked":false,"published":"2024-04-06T08:41:56.187248Z","deleted":false,"nsfw":false,"embed_title":"Type Inference Was a Mistake","embed_description":"On type inference as an academic computer science lab leak.","thumbnail_url":"https://programming.dev/pictrs/image/ac13ba61-887f-4b8f-bf8f-1afa7b3faf54.webp","ap_id":"https://programming.dev/post/12428069","local":false,"language_id":37,"featured_community":false,"featured_local":false},"community":{"id":188907,"name":"programming_languages","title":"Programming Languages","description":"Hello!\n\nThis is the current Lemmy equivalent of https://www.reddit.com/r/ProgrammingLanguages/.\n\nThe content and rules are the same here as they are over there.
