TIL about the box.leak() method in Rust: https://doc.rust-lang.org/std/boxed/struct.Box.html#method.leak
This leaks the box, but it also gives you a reference that can live longer! E.g. you can leak a Box<u64> and treat it as 'static.
It makes sense, but being able to use a value after leaking is new idea to me.

I'm intrigued to see that Google has quantified that new code is generally buggier and less secure than code that has existed in your codebase for longer:
C++ no longer considers trivial infinite loops to be undefined behaviour! https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2024/p2809r3.html
Spotted in the release notes for the latest clang.
I've added basic sum types to my programming language project, and it simplifies a bunch of stuff. Bool and Unit no longer need to be built-in types!
I'm now working on wrapped data, so I can implement Option :)
