Yes. sync.WaitGroup.Wait would be useless if it didn't provide a happens-before relationship from changes made in the goroutine that calls Done to the goroutine that calls Wait. I suppose this could be documented in the docs for sync.WaitGroup, but it also kind of falls under the "Go is not trying to trick you" rule.
