Yes, good point, a switch from a GC-based language to a memory ownership -based language is definitely non-trivial, but you can always just forget Rust references altogether for the time-being and start hacking with Rust with its reference-counted smart pointers, effectively learning Rust as if it were Go. (You will have to switch back to Rust ownership/references later on to get back the performance and the respect of other Rustaceans 8) .)
