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)
