Go has certainly come a long ways from its initial mission to be a simple language for Rob Pike's simple coworkers.

    type User struct {
        Name     string `json:"name"`
        Password string `json:"-"`
        Email    string `json:"email"`
    }

So you can specify how to serialize a struct in json using raw string literals containing arbitrary metadata. And json:"X" means to serialize it to X, except the special value "-" means "omit this one," except "-," means that its name is "-". Got it.

Of all the things one might critique Go for as not being simple, I'm not sure this is it. I've never needed to serialize "-" as a key in JSON but `-,` makes some sense given the general pattern of field tags, e.g. `json:"name,omitempty"`
