There is no one answer to that question. As you know, `nil` is the value of an uninitialized variable of interface, slice, pointer, map, function, or channel type. Beyond that it has no shared meaning. For each of those types, the value `nil` behaves differently, in a way that makes sense for the type. See also https://golang.org/issue/22729.
