That's the main use-case of Erlang/Elixir anyway: eliminate concurrency / parallelism bugs by copying data in the dangerous places, and make sure not to use locks but message passing instead. These two alone have eliminated most of the bugs I've wrote in other languages. So, same experience. And it taught me to be a better Golang and Rust programmer, too.
