> Theoretically you can have a good candidate that doesn't know e.g. that appending to a slice passed in a function argument is a recipe for disaster. Huh? This is a common pattern. (hash.Hash).Sum, strconv.AppendInt, etc. I think you're referring to the fact that append can mutate existing memory (that is, it doesn't always allocate new memory), but in practice, this is rarely an issue, because, by convention, functions that append to a slice always return that slice.
