> fighting the borrow checker
My experience is that this is an initial hurdle to clear. As an example, I've almost exclusively worked in GC'd languages for a while, and after learning Rust for a few months I very very rarely have borrow check errors.
The fact that it occasionally requires a complex pattern to do right should get better with time (non-lexical lifetimes would help), and there's also discussion around GC integration so that you could interact with a scripting language GC when writing a plugin for it, or you could farm out GC'd objects when you need to have cycles (i.e. in graph algorithms).

Interesting. I'm curious how much of the browser relies on it. I'm also curious whether it's an attempt to paper over C++ with a little memory safety, or whether it actually offers performance improvements. My original point was not that GC is bad, per se, but that I quite like being able to avoid it when it's reliable to do so, which is not the case in C++, IMO.
