I strongly disagree that smart pointers are "off the paved road". I don't even care to make specific arguments against that notion, it's just a terrible take.

No, not really. Firstly, there is no significant "friction" to using Rust smart pointers and internal mutability primitives, as those constructs have been added to Rust for a reason: to solve certain borrow checker edge cases (e.g., multiply interconnected data structures), so they are treated by the Rust ecosystem as first-class citizens. Secondly, those constructs make a pretty good educational tool. By the time people get to know Rust well enough to use those constructs, they will inevitably realize that mastering the Rust borrow checker is just one book chapter away to go through out of passion or boredom.

I find quite a lot of friction in being demanded to understand all of the methods, what they do, when you’d use them, why you’d choose one over another that does a slightly different thing, but maybe still fits.

The method documentation alone in reference counting is more pages than some entire programming languages. That’s beside the necessary knowledge for using it.

I don't think it's necessary to understand every single `Rc<T>` method[1] to use Rust smart pointers to learn Rust. Perhaps try a different learning resource such as "Rust By Example"[2], instead?

It's telling people to avoid the famously hard meme-road.

Mutexes and reference counting work fine, and are sometimes dramatically simpler than getting absolutely-minimal locks like people seem to always want to do with Rust.

Reference counting and locks often is the easy path in Rust. It may not feel like it because of the syntax overhead, but I firmly believe it should be one of the first solutions on the list, not a last resort. People get way too fixed on trying to prove to the borrow checker that something or another is OK, because they feel like they need to make things fast, but it's rare that the overhead is actually relevant.

Yes! Thank you! Dunno what it is about Rust that makes everyone forget what premature optimization is the root of all of.

The zero cost abstraction is so tantalizingly close enough to reach!

I tell everybody to .clone() and (a)rc away and optimize later. But I often struggle to do that myself ;)

If it's syntactically messy, though, it's not really the easy path. Ergonomics matter just as much as semantics.

I do think that a superset of Rust that provided first-class native syntax for ARC would be much more popular.
