Heh, I did the opposite recently after reading "Software Engineering at Google" and I discovered that even though it would be very easy to make: there is no equivalent to the `go/` permanent "friendly" URL shortener.
It can be backed by a TOML file for hardcoding URLS or a database for making it easy to add new ones (which I think is the Google way).
If I did a stupid; or a better version already exists: let me know.
