You're not being very precise about your exact issues. `nil` isn't anywhere as much of an issue in Go as it is in Java because not everything is a reference to an object. A struct cannot be nil, etc. In Java you can literally just `return null` instead of an `Optional<T>`, not so in Go.

There aren't many possibilities for nil errors in Go once you eliminate the self-harm of abusing pointers to represent optionality.
