Well, I'd appreciate a writeup explaining this, if/when you have the time and inclination 🙂

Your answer make it sound like places are always on the stack? The heap isn't a place?

That's not intuitive to me, sorry. I don't understand how this relates to something that can be passed between threads, because it is SOMEthing, so there must be a place that contains it.
IMO the lifetime metaphor fits static better. "It's valid, because it's always alive" is easy.

Fair enough, but what's the intuitive explanation for static, in this POV?

I'm not exactly sure what you're asking here, but it sounds like a problem that mockito solves.

Succeed. If you want to force an at least 1 condition, it should be defined in the attribute argumenta.

After reviewing, feedback, and more review, I gave up. It was frustrating to harangue claude to REPLACE ALL THE STRINGS, YES THAT ONE TOO, and also to ensure that it should keep `Result`s, instead of finding "clever" ways to avoid returning errors.
Claude just wants to have strings, I guess.

On the journey, it deleted the whole test suite of one class, and as mentioned, got completely stuck once, which required a manual edit of the code.
On the other hand, after 2 hours the change was complete - I just need to review the change.

Claude just moved the logic around, but still used the combined string throughout the code, until I explicitly told it to delete / change the inputs on every function that takes a string.

The change isn't very complex - the code splits addresses to host + port, but then saves those addresses as `format!("{host}:{port}")`, only to split them again when the address is used. I just wanted to save the split value, instead of combining and splitting again.

The code didn't compile, with the error
```
error[E0765]: unterminated double quote string
--> path/to/file.rs:464:57
```
and Claude just couldn't fix the issue, probably because it originated on the other side of the file, in line 130:
`if let Some(bracket_end) = addr.find("]:') {`

Really impressive. Any plan to have named enum variants, like Rust has? Relying on unique types per variant is a pain point of std::variant that exists here, too.

Somewhat less realistic when discussing the indexing operator for hashmaps without knowledge of keys. You created a map from a deserialized JSON - don't make assumptions on its contents.
