That's handy: an empty interface can hold any value and contains all the information we could ever need about that value. (We don't need a type assertion here because it's known statically that `w` satisfies the empty interface. In the example where we moved a value from a `Reader` to a `Writer`, we needed to be explicit and use a type assertion because `Writer`'s methods are not a subset of `Reader`'s.) |
