yeah I mean rust Rc<>, I don't have experience with lobster, does it allow mutation from multiple places or does it panic just like rust?

- throw10920 5y agoThe latter - although as a sibling commentator pointed out, it doesn't do cycles - so it's better, but not a panacea.
- cztomsik 5y agoAh, ok, having cycles is another problem, also hard, but my point was about multiple mutable references which is not a safety problem if you have GC. You only get race conditions. And I think it could/should work also with Rc<> but for some reason, rust authors decided it's important to write everything as if it was multi-threaded even if it's single-threaded now (so it can be easily turned to multi-threaded later). And that's cool but it adds a lot of burden to developers. I am probably missing something, there is likely a good reason for this, as always, but it doesn't change the point, rust is super-complicated for hobby stuff and you have to think about irrelevant things, hence for me, it is low-level language (with generics and macros and very cool builtin unit testing but it's still low-level) And by irrelevant I don't mean mem-safety, that IS important for me, I rather mean worrying about race-conditions in a single-threaded code :)
