Usually, the `interface{}` is named something like `Xer` to denote an interface which satisfies `X`. So - `Dialer` would be the interface and any struct is free to implement the `Dialer` methods to qualify as one (for example). Presumably requiring some way to `Dial` something.

What I like most about `go` is how standard a lot of the "good practices" are, with a focus on getting stuff implemented. There is no time to argue about spacing and bracing, just run `go fmt`.
