Systemctl (systemd) zsh autocomplete

Question

Has anyone created a zsh command completion script for systemctl? If so, would you mind sharing on the AUR?
In my mind, it should work like so:
systemctl en[TAB] wic[TAB]
#evaluates to
systemctl enable wicd.service
systemctl rest[TAB] get[TAB][TAB]
#evaluates to
systemctl restart getty@tty
[email protected]   [email protected]   (etc)
For {COMMAND}, it should obviously expand to list-units, start, stop, reload, restart, try-restart, reload-or-restart, reload-or-try-restart, isolate, kill, is-active, status, show, reset-failed, enable, disable, is-enabled, load, list-jobs, cancel, monitor, dump, dot, snapshot, delete, daemon-reload, daemon-reexec, show-environment, set-environment, unset-environment, default, rescue, emergency, halt, poweroff, reboot, kexec, or exit.
As for [NAME...], it's gonna be a lot more complicated. Depending on the COMMAND, it should search through the relevant files in /lib/systemd/system/ and /etc/systemd/system, or the currently enabled services, or the currently running services, etc.
If nobody's made/in the process of making something like this, I'll give it a go when I have the time. Although I'd probably just focus on the start, restart, stop, enable, disable, poweroff and reboot, since those are the only commands I use.

Awesome, thanks. I did make a start on my own, but I couldn't get it to work properly. You might want to write up a PKGBUILD and submit it to the AUR so more people can find it (here's the PKGBUILD I wrote up to install it on my PC, which'll save you ~20 seconds of writing).
AUR submission instructions are here.
