This is a poor argument. You dont write code like this in rust. If you can find a situation where it is an actual issue we can discuss things but to just say imagine this is a problem when it very likely is not a problem that can be solved in a better way at all let alone a common one is a very poor argument.

Typically when you want an escape from lifetimes that means you want shared ownership of data which you can do with an Arc. Cow and LazyLock can also help in situations - but to dismiss all these for some imagined problem is a waste of time. Comes up with a concrete example where it would help. Very likely you would find another way to solve the problem in any realistic situation you can come up with that I would suspect leads to a better overall design for a rust program.

I would say this is just a straw man argument - but you have not even created a straw man to begin with, just assume that one exists.

I perfectly agree, that would be horrible code! I would generally try to restructure my code, making it better fit the actual lifetimes of the data I'm working with. The point in the article is that you can't really escape from this. I'm not arguing this is a real problem, and I don't think the article is neither, just pointing out that this is something you can easily do in C# and not in Rust. It's just a difference between the two languages.

What? You can easily escape from it if there are better alternatives you can use. Pointing at one language and saying it is not easy to code like it is another language is a pointless argument. You can do that about any two languages. They all differ for good reasons and as long as you can solve similar problems in both, even if in different ways then what does it matter that you cannot do it in the same way?

So there is no general escape hatch.

Pointing at one language and saying it is not easy to code like it is another language is a pointless argument.

I'm not arguing that it is easier to code in C# than in Rust, just that this particular escape hatch is possible in C# and not in Rust. It's just an observation.

It does not really matter, but does it have to?
