// iris context implements the io.Writer by its ResponseWriter
// which is an enhanced version of the standard http.ResponseWriter
// but still 100% compatible, GzipResponseWriter too:
// _, err := template.UserListToWriter(userList, ctx.GzipResponseWriter())
buffer := new(bytes.Buffer)
template.UserList(userList, buffer)
