The most ugly #trick in #rust language, which #plt people will completely dislike. Let's assume we need to write macro a!, which determines whether given expression implements given trait Value. If yes, it should print "Yes", if no - "No". Surprisingly, this is possible in Rust. By completely abusing method call expression rules ( https://doc.rust-lang.org/nightly/reference/expressions/method-call-expr.html ). Here is solution: https://github.com/tokio-rs/tracing/pull/2781#issuecomment-1785862587 . I think existence of such trick proves that Rust is not perfect language.

UPD: This method is called autoref specialization

Many developer hesitate to implement searching feature on Mastodon, and me. Social pressure is going to be harder if everybody could search someone's past voice. Our fresh brain don't collect and purge garbage rather than ruby do. We build a virtual image of human from a single toots without context and could adhere on it. Let forget them.
SFF could show this apprehension in strong narrative, I imagine.
