I don’t think it’s unexpected that a
reprattribute changes the memory representation.

/u/Gankro's "hacking generativity onto Rust" (section 6.3 here) and bluss's implementation. This is some of the most horrifying code I've ever seen, up there with Duff's device in C and partitioning lists in Python.
Basically, you can use lifetime-based black magic fuckery to move bound checks to compile-time.
Rust: you had my curiosity, but now you have my attention.
From this Reddit comment responding to "What is your favorite Rust code snippet?". It's full of links that I'm too lazy to copy over, but those links make it very informative (and funny).

But aren't we all just objects in a global scope?
Not in Rustland. We only have good Traits.

scott: see, at christmas, if I unwrap() my present and I find that it's empty, I immediately have a panic attack and everyone gets really freaked out. if I expect() a present, at least I can send a stern message before I start panicking in the living room.
scott: sometimes I decide ahead of time that if I start having a panic attack, I'm just going to abort the whole christmas thing entirely and leave
scott: but it's easier to unwind if I don't abort and stick around

If you've seen the if programming languages were people cartoon, you'll remember Rust being portrayed as a knight with three shields and a witty message. I like to think of error_chain as a squire loyal to the Rust knight.

I would argue that if the Rust project would have just one mission statement, it wouldn't be "create a safe systems programming language". It would be "move towards a world where safe systems programming is the norm".

This is the first version to have Rust code in it. The public API
remains unchanged. Apologies in advance to distros who will have to
adjust their build systems for Rust - it's like taking a one-time
vaccine; you'll be better off in the end for it.

One of the core tenets of C++ is "trust the programmer". One of the core tenets of Rust is "the programmer is a complete numpty; don't trust them unless they sign a contract in blood, in triplicate, promising they know what they're doing."
People make mistakes; Rust asks if you're sure you want to walk into the minefield, C++ enthusiastically runs ahead and blows all its limbs off while screaming "I don't know why you asked me to do this, but anything to make you happy!"

Mh I'd like a sarcastic-dissapointed compiler like
use of moved value: 'val'. Again. There goes my hope you learned that by now. Serously. It's not that hard...
(...)
error: could not compile 'foo'. Maybe try a garbage-collected language?
