Repeating a command with sudo

Sometimes I forget to run a command as sudo. Bash comes to help and can
repeat the previous command:

$ pacman -Suy docker
Sorry, you need to be root to execute docker.
$ sudo !!
sudo pacman -Suy docker
[sudo] passord for jans:
...
$

!! can also be used to repeat the previous command.
