A big problem with both Rust and Go is that the marketing says there are no exceptions, and because we all know exceptions are bad/slow/hard to understand that the languages are superior. I strongly object to this idea because from an implementation POV both Go and Rust are 90% there for all the complexities that exceptions cause but now nobody is aware of it.

(This is also why I'm a huge proponent of Results in Rust and disabling unwinding altogether)

Well, as I said earlier, stack unwinding does not imply that the stack unwinding is NORMAL; I'm fine with it in exceptional cases.

Defer has its own quirks that irritate me but I wouldn't call them exceptional so much as dynamic RAII.... or something.

Either way, if the languages allow me to avoid tracking down every possible http connection exception I need to trap to avoid bringing down my process I'd say it's a net win.
