you can voluntarily write Go which doesn't share any state, although clearly if thats an invariant you'd like to keep it would be really nice for the language to enforce it for you.

more importantly I've found that as you grow such Go programs, write higher-order actors, and deal with all the error/cleanup cases, the selects start to get really brittle and you end up spending alot of time refactoring them and carefully going over all the edge cases.
